Nursing School Admissions — NursingCAS
Nursing School GPA — Overall & Science,
all attempts counted.
Enter every undergraduate course — science prerequisites and non-science. The calculator splits your GPA into Overall and Science GPA matching how NursingCAS works. Tag anatomy, physiology, microbiology, chemistry, and biology as "Science."
How to use this calculator
Four steps to your
accurate NursingCAS GPA
NursingCAS tracks Overall GPA, Science GPA, and a per-program Prerequisite GPA. The Prerequisite GPA is what most nursing programs actually screen on first — follow these steps to make sure your estimates reflect what programs will see.
Tag nursing science prerequisites as Science — non-science prereqs as Other
Anatomy & Physiology (both semesters), Microbiology, General Chemistry, Nutrition, and General Biology are Science courses in NursingCAS. Psychology, Sociology, English Composition, and similar liberal arts prerequisites go into Non-Science. Statistics may count as Science or Math depending on how NursingCAS classifies it — if your program requires it, tag it as Science to approximate your Science GPA for that prerequisite cluster. The Science GPA this calculator produces represents your performance in the courses nursing curricula are built on.
Enter every prerequisite attempt — retakes included, exactly as NursingCAS policy requires
NursingCAS officially does not recognize academic forgiveness, grade replacement, or renewal policies. The policy is verbatim: "All grades earned for repeated courses are factored into your NursingCAS School GPA." If you retook Anatomy after a C and earned an A, add two rows: C (4 credits) and A (4 credits). The original C stays in the calculation. This is especially important for Anatomy & Physiology — a 6–8 credit prerequisite where a retake has significant impact on your Science GPA estimate.
Check each program's minimum grade per prerequisite — Science GPA alone isn't enough
Most nursing programs require a minimum grade (usually C or C+, sometimes B) in every individual prerequisite course — not just an acceptable overall Science GPA. A Science GPA of 3.2 with a D in Microbiology may disqualify you from programs requiring C or better in all prerequisites, even though your average looks competitive. Before applying, check each program's per-course grade minimums in NursingCAS's school directory. This is a different screen from the cumulative Science GPA and often the reason applicants with solid overall numbers still get rejected in preliminary review.
Understand that Prerequisite GPA differs from Science GPA — it varies by program
Your Science GPA covers all courses in Biology/Chemistry/Physics categories across all institutions. Your Prerequisite GPA is calculated by NursingCAS specifically for each program based on that program's designated required courses. If a program requires Anatomy, Physiology, Microbiology, and Chemistry — and you have a D in Microbiology but As in everything else — your Prerequisite GPA for that program reflects that D directly. The Prerequisite GPA can differ significantly between programs even when your overall Science GPA is stable. This calculator gives you Science GPA; check program-specific fits by reviewing your grades in each program's exact prerequisite list.
How it works
Two GPAs, one nursing application —
here's what NursingCAS calculates
NursingCAS — the Centralized Application Service for Nursing programs — recalculates your GPA from scratch. Every graded course from every institution is converted to a standard 4.0 scale, including all retakes, with no grade replacement. Nursing programs typically receive three GPA measures: Overall GPA, Science GPA, and a Prerequisite GPA tailored to each program's specific required courses.
The Overall GPA covers every graded undergraduate course. The Science GPA covers Biology/Chemistry/Physics and Other Science subject categories — the core sciences that nursing prerequisites fall into. The Prerequisite GPA is calculated per-program and covers only the specific courses that program lists as required prerequisites, so it can differ from your overall Science GPA.
This calculator computes Overall GPA and Science GPA — the two measures most commonly referenced in published nursing program admission data. Source: NursingCAS GPA Calculations.
The formula
| GPA type | What goes in | Formula |
|---|---|---|
| Overall GPA | All graded undergraduate courses, all institutions | Σ(grade pts × credits) ÷ Σ(credits) |
| Science GPA | Biology/Chemistry/Physics and Other Science courses | Σ(grade pts × credits) ÷ Σ(science credits) |
No grade replacement
Official NursingCAS policy verbatim: "NursingCAS does not recognize an individual school's policies for forgiveness, academic renewal, or grade replacement for repeated courses. All grades earned for repeated courses are factored into your NursingCAS School GPA."
Worked example
NursingCAS Science GPA in practice
Five courses — a key nursing prerequisite retake, two science courses, and two non-science courses — showing exactly how the two GPAs differ.
| Course | Type | Grade | Cr | Points |
|---|---|---|---|---|
| Human Anatomy & Physiology I | Science | C+ | 4 | 9.2 |
| A&P I (retake) | Science | A− | 4 | 14.8 |
| Microbiology | Science | B+ | 3 | 9.9 |
| English Composition | Other | A | 3 | 12.0 |
| Developmental Psychology | Other | A | 3 | 12.0 |
Overall GPA: (9.2+14.8+9.9+12.0+12.0) ÷ 17 = 57.9 ÷ 17 = 3.41
Science GPA: (9.2+14.8+9.9) ÷ 11 = 33.9 ÷ 11 = 3.08
The A&P retake helps — the A− adds 14.8 quality points — but the original C+ (9.2 pts) still counts. A straight A in A&P without the retake would have been (16.0 + 9.9) ÷ 7 = 3.70 Science GPA. This shows how a single early weak grade in a core nursing prerequisite has lasting impact.
Science prerequisites
The science courses nursing programs
require — and how they count
The nursing science prerequisites that go into your Science GPA are the same courses nursing school is built on. Strong performance here signals readiness for the clinical science content of nursing school — Pathophysiology, Pharmacology, and Medical-Surgical Nursing all require the foundation these courses build.
| Course | NursingCAS type | Notes |
|---|---|---|
| Human Anatomy & Physiology I & II | Science ✅ | Nearly universal prerequisite; 2-semester sequence |
| Microbiology (with lab) | Science ✅ | Required by most BSN and ADN programs |
| General Chemistry I | Science ✅ | Required by many BSN programs; less common for ADN |
| Nutrition | Science ✅ (Other Science) | Required by many programs; counts as Science in NursingCAS |
| Statistics / Biostatistics | May vary by program | Often required; may count as Math in some classifications |
| Developmental/Lifespan Psychology | Non-Science | Common prerequisite; goes into Non-Science GPA |
| Sociology or Cultural Anthropology | Non-Science | Required by some programs; counts as Non-Science |
| English Composition | Non-Science | Often required; Non-Science GPA |
Prerequisites vary by program. Use this as a guide — confirm each program's specific requirements in NursingCAS's school directory before planning your coursework.
Grade scale
How NursingCAS converts
your grades to GPA points
NursingCAS uses a standard 4.0 scale with plus/minus grades. Your school's grade-point values are not used — NursingCAS converts all grades to its own scale. Source: NursingCAS GPA Calculations.
| Letter grade | GPA points | Admissions context |
|---|---|---|
| A+ / A | 4.0 | Target for all science prerequisites |
| A− | 3.7 | Excellent; strongly competitive |
| B+ | 3.3 | Above average; acceptable in most courses |
| B | 3.0 | Average — consistent B's keep you competitive |
| B− | 2.7 | Slightly below — consider strengthening in key science courses |
| C+ / C | 2.3 / 2.0 | Some programs require C or better in each prerequisite |
| C− / D | 1.7 / 1.0 | Below passing threshold for many programs; retaking is advisable |
| F | 0.0 | Counted in GPA even after retaking |
| W | — | No grade points; doesn't affect GPA directly |
Where you stand
Nursing school GPA benchmarks —
BSN, ADN, and ABSN
GPA requirements vary significantly between program types. ADN (community college RN) programs are generally more accessible; BSN and ABSN programs at universities are more competitive:
| Program type | Typical GPA range | Science GPA expectation |
|---|---|---|
| ADN (Community College) | 2.5 – 3.2+ for competitive admission | 2.5+ in all prerequisites |
| BSN (Traditional, 4-year) | 3.2 – 3.7+ depending on school | 3.0 – 3.5+ |
| ABSN (Accelerated, career changers) | 3.0 – 3.5+ typically required | 3.2+ in all nursing science prerequisites |
| MSN-entry programs (for non-nurses) | 3.0 – 3.5 or higher | Strong prerequisite science performance |
Many programs also require a minimum grade (usually C or B) in each individual prerequisite — not just an acceptable overall Science GPA. A B average Science GPA with a D in Microbiology may disqualify you from programs that require C or better in every prerequisite. Check each program's specific grade minimums.
Achievability scenarios
Prerequisite-GPA threshold —
why individual course minimums matter as much as averages
Nursing programs use two GPA screens simultaneously: a cumulative Science GPA and a per-course grade minimum for each prerequisite. These three applicants show how the two screens interact — and why a solid Science GPA average doesn't guarantee you'll clear every program's threshold.
Maria — Science GPA 3.25, Every Prereq Above C+, TEAS 82
Maria's NursingCAS Science GPA is 3.25 — below the national average for competitive BSN programs but carefully built with no prerequisite grade below C+. She retook Anatomy & Physiology I after an original C (3.0→2.3 averaged to 3.1 for that course cluster), earned B+ in Microbiology and B in Chemistry. TEAS score: 82 (Advanced level).
No prerequisite below C+ — all per-course minimums cleared
TEAS: 82 (Advanced)
Healthcare exp: CNA, 400 hrs acute care, 1 yr
Maria applies to 12 BSN programs — 4 community-based BSN, 6 regional university BSN, and 2 ABSN programs for career changers. Her Science GPA of 3.25 is below the 3.4 median at some competitive programs, but her TEAS score of 82 strengthens her composite score. More importantly, she clears every program's per-course prerequisite minimum. She receives interview invitations at 5 programs and accepts an offer at a regional BSN program whose average admitted Science GPA is 3.2.
Kwame — Science GPA 3.4 but D in Microbiology Blocks 60% of Programs
Kwame's overall Science GPA is 3.40 — above average, with strong performance in Anatomy (A−), Chemistry (A−), and Biology (A). But he earned a D in Microbiology during a difficult semester and never retook it, reasoning that his strong overall Science GPA would compensate. Microbiology was a 3-credit course; its D contributes 3.0 quality points where 12 would have come from an A.
Microbiology: D (1.0 × 3 cr = 3.0 quality points)
Programs requiring C or better in each prereq: ~18 of 25 applied
Programs eligible for after D: ~7 of 25
Of the 25 programs Kwame applies to, 18 require C or better in every prerequisite — Kwame is automatically screened out of all 18 before his 3.40 Science GPA is ever considered. He receives review at only 7 programs that either don't specify per-course minimums or list D as passing. He doesn't match at any. The fix is straightforward: retake Microbiology, earn a B or better, and reapply next cycle. The retake's B would bring the Microbiology cluster to (3+10.5) ÷ 6 = 2.25 — not strong, but above the C threshold. Kwame reapplies next cycle, passes all per-course minimums, and matches on the second application.
Taylor — Science GPA 2.6, Three Prerequisites Below Program Minimums
Taylor has three prerequisite grades below C: a D in Anatomy I, a D+ in Microbiology, and a C− in Chemistry I. Their overall Science GPA is 2.61. They've completed nursing shadowing and hold a hospital volunteer position, but haven't retaken any of the weak prerequisites.
Microbiology: D+ (1.3 × 3 cr = 3.9 pts)
Chemistry I: C− (1.7 × 4 cr = 6.8 pts)
Science GPA: 2.61 — below most BSN program minimums
Taylor is below the published minimum for most BSN programs (typically 2.75–3.0 cumulative Science GPA) and fails the per-course grade minimum for the three courses most programs require. Applying now means near-certain rejection across all programs. The realistic path: retake all three courses in one academic year. If Taylor earns A/A− in each retake (all three at 3.85 avg × 11 cr = 42.35 pts), the Science GPA rises from approximately 2.61 (assume 33 total credits = 86.1 pts) to (86.1 + 42.35) ÷ 44 = 2.92 — above ADN minimum thresholds, still below many BSN medians. A second year of continued strong performance brings the Science GPA to the competitive range for regional BSN programs.

Frequently asked questions
Nursing school GPA — your questions answered
Does NursingCAS count both grades when I retake a prerequisite?
Yes. NursingCAS's official policy states: "NursingCAS does not recognize an individual school's policies for forgiveness, academic renewal, or grade replacement for repeated courses. All grades earned for repeated courses are factored into your NursingCAS School GPA." If you retook Anatomy after a C and earned an A, both the C and the A go into your NursingCAS GPA — both count in the credit-weighted formula. The A genuinely helps (adds 4.0 quality points per credit), but the original C's contribution doesn't disappear. Source: NursingCAS GPA Calculations.
What is the minimum GPA for nursing school?
Published minimums vary by program type and institution. ADN programs at community colleges often list 2.0 or 2.5 as a minimum but admit based on competitive GPA ranking among applicants. BSN programs at universities typically require 2.75–3.0+ to apply, with competitive admitted classes averaging 3.3–3.6. ABSN programs often require 3.0+ in prerequisite sciences as a minimum. Don't rely on minimums — the key number is the average GPA of recently admitted students, which tells you where you're actually competitive. Most programs publish this data online or will share it if you contact admissions.
How important is Anatomy & Physiology for nursing school admissions?
A&P is the single most important prerequisite for nursing admissions in most programs. It's required at virtually every nursing school, it's the largest science course you'll take as a prerequisite (often 6–8 credits across two semesters), and it's the most direct predictor of readiness for nursing school's core science content — Pathophysiology, Pharmacology, and Medical-Surgical Nursing all build directly on it. A strong A&P grade (A or A−) is the highest-return investment in your nursing application. If you earned a C, retaking it is almost always the right move before applying.
What is the TEAS test and how does it affect admission?
The ATI TEAS (Test of Essential Academic Skills) is a standardized test covering Reading, Math, Science, and English that many nursing programs require alongside GPA. It's scored from 0–100%, and programs typically classify 70%+ as "Proficient" and 80%+ as "Advanced." The Science subtest covers Biology, Chemistry, Anatomy and Physiology, and Life/Physical Sciences — directly related to your nursing prerequisites. Many programs combine TEAS score with GPA into an index score for initial ranking and selection. A strong TEAS score (78–85+) can strengthen an application with a slightly below-average GPA.
Is the ADN-to-BSN bridge worth doing?
For most nurses, yes — eventually. Hospital employers increasingly prefer or require BSN-prepared nurses for hire and advancement. The ADN path makes sense when: you need to work as an RN sooner (ADN takes 2 years vs. 4), your undergraduate GPA doesn't support direct BSN admission, or you're cost-conscious (community college ADN programs are significantly less expensive). RN-to-BSN bridge programs are widely available, often online, and many hospitals offer tuition reimbursement for nurses completing their BSN while working. Plan for the bridge from the beginning — it's expected, not an afterthought.
How do I calculate my prerequisite GPA for nursing school?
Your Prerequisite GPA in NursingCAS is the credit-weighted average of only the courses that a specific program has designated as its prerequisites. To estimate it: list the specific courses that program requires, find your grade and credit hours for each, and run the calculation: Σ(grade points × credits) ÷ Σ(credits). In this calculator, you can approximate it by entering only your prerequisite courses and labeling them all as "Science" — then the result panel's Science GPA approximates your prerequisite performance. Remember that this will vary by program since each program has its own prerequisite list.
Do nursing programs look at GPA trend or just cumulative GPA?
Both matter. Admissions committees read transcripts, not just GPA numbers — a 3.3 GPA achieved by improving from a 2.5 freshman year to a 3.8 senior year tells a very different story than a flat 3.3 throughout. An upward trend, particularly in science prerequisites, demonstrates that you've developed the academic habits and scientific literacy needed for nursing school. A downward trend — strong early, weaker later — raises questions regardless of the cumulative number. When writing application essays, address any downward trends proactively and explain the upward recovery.
Can online prerequisite courses count for nursing school?
Online coursework that appears on your official transcript with a letter grade counts in your NursingCAS GPA the same as in-person courses. However, many nursing programs require in-person or hybrid labs for Anatomy, Physiology, Microbiology, and Chemistry — online lecture with in-person lab is often acceptable, but fully online lab courses may not satisfy the lab requirement. Check each program's specific policy on online prerequisites — some accept them, others require in-person, and many are silent on the distinction (which usually means check with admissions).
What makes a nursing school application competitive beyond GPA?
Beyond GPA and TEAS, competitive nursing applications include: healthcare experience (CNA, medical assistant, EMT, hospital volunteer — the more hands-on the better), a compelling personal statement that articulates why nursing specifically, strong letters of recommendation from science faculty or healthcare professionals who know you in a clinical context, and alignment between your background and the program's focus (community health programs value community work; acute care programs value hospital experience). Nursing programs are also attentive to demonstrated commitment — people who've been working in healthcare, not just taking prerequisites.
How many nursing schools should I apply to?
The right number depends on your target program type. For BSN programs via NursingCAS: applying to 5–15 is typical for a competitive applicant (3.4+ GPA). For a below-average applicant (2.8–3.2 GPA), applying to 10–20 programs — including a mix of BSN and ADN programs — provides more options. Don't over-apply without researching each program — a tailored personal statement for specific programs performs better than generic applications to 30 schools. NursingCAS verifies your application once and sends it to all programs you designate, making the logistics of a broader list manageable.
What is the NCLEX-RN pass rate, and does it matter for choosing a program?
The NCLEX-RN is the licensing exam every RN must pass after completing nursing school. First-time pass rates vary by program — from roughly 70% at some programs to 95%+ at others. Most state nursing boards publish NCLEX pass rates by program annually. A program's NCLEX pass rate is one of the clearest indicators of program quality and preparation, and it should factor into your school selection alongside acceptance rates, location, cost, and clinical rotation opportunities. Programs with below-85% pass rates deserve additional scrutiny.
