Most schools set a Science stream cutoff between 60% and 80% aggregate after Class 10. But aggregate is only the first of three checks. Schools also apply a separate minimum for Science marks and another for Mathematics. A student with 78% overall but 52% in Science can still face rejection. This applies across CBSE, ICSE, Kendriya Vidyalaya, and all state boards. Each school sets its own subject-level thresholds. Knowing all three filters before results day puts your family ahead.
This post is verified for the 2025–26 admission season. It maps board-wise cutoffs across CBSE, ICSE, KV, and state boards. It also explains what parents should do on results day — whether your child clears every filter or misses one.

⚡ Key Takeaways for Busy Parents
| What Most Parents Believe | What Actually Happens at Admission |
|---|---|
| One aggregate cutoff decides everything | Schools apply 3 filters — aggregate, Science marks, Maths marks |
| 80% means guaranteed Science admission | 80% with low subject scores can still result in rejection |
| All CBSE schools use the same cutoff | Every school sets its own cutoff — top vs. mid-tier vary by 15–20% |
| Missing cutoff means no Science stream | Multiple school options and board changes remain open post-results |
| ICSE and CBSE use the same formula | ICSE scores are calculated differently — schools convert or weigh them separately |
The Three Cutoffs Schools Actually Check
Admission to Science stream — whether PCM (Physics, Chemistry, Mathematics) or PCB (Physics, Chemistry, Biology) — is never decided by one number. Schools run your child’s marksheet through three distinct filters. Most parents only know about the first one.
Filter 1 — The Aggregate Percentage
This is the total percentage across all subjects. Schools publish this as their headline cutoff. You will see it on school notice boards and admission brochures. It ranges from 55% at tier-3 schools to 90%+ at elite metro institutions. But clearing this filter only gets you to the next check.
Filter 2 — The Science Subject Minimum
Most schools require a minimum score in Science at the Class 10 level — typically 55% to 70% in Science, depending on school tier. This filter catches students whose high aggregate hides a weak Science performance. A student with 82% overall but 54% in Science will often be declined for PCM stream, even at a school with a 70% aggregate cutoff.
Filter 3 — The Mathematics Minimum (for PCM)
For students choosing PCM (the engineering-track stream), schools add a separate Maths cutoff. This is usually 55% to 70% in Mathematics. PCB students are often exempt from this filter. Schools rarely publish this third filter openly — which is exactly why so many families are caught off guard on admission day. If your child’s Maths score is a concern, read our post on why CBSE Maths questions feel hard — and how to close that gap.
Board-Wise Science Stream Cutoffs for 2025–26
Cutoffs vary significantly across boards and school tiers. The table below gives you a working benchmark. Always verify against your specific school’s published admission notice for 2025–26. For a deeper understanding of how CBSE Class 10 marks are calculated and what scores mean on the marksheet, see our guide on minimum passing marks in CBSE Class 10.
CBSE School Cutoffs
| School Tier | Aggregate Cutoff | Min. Science | Min. Maths (PCM) |
|---|---|---|---|
| Top-tier (Metro) | 85% – 95%+ | 75% – 85% | 80% – 90% |
| Mid-tier | 70% – 84% | 60% – 74% | 65% – 75% |
| Tier-3 / Private Unaided | 55% – 69% | 50% – 59% | 50% – 60% |
ICSE School Cutoffs
ICSE Class 10 results use a slightly different marking structure. Many ICSE-affiliated schools offering Class 11–12 (ISC board) calculate aggregate differently — often using best-of-five subject scores. Schools that switch from ICSE to CBSE for Class 11 may convert your child’s marks before comparing.
| School Tier | Aggregate Cutoff | Min. Science | Min. Maths (PCM) |
|---|---|---|---|
| Top-tier | 80% – 92%+ | 75% – 85% | 75% – 88% |
| Mid-tier | 68% – 79% | 60% – 74% | 62% – 72% |
Kendriya Vidyalaya (KV) Cutoffs
KV schools follow centrally issued admission guidelines. For Science stream, the benchmarks are generally more uniform across schools compared to private institutions. Note that KV admission is also subject to category reservations (SC/ST/OBC/EWS) which can shift the effective cutoff.
| Stream | General Category | Min. in Science | Min. in Maths |
|---|---|---|---|
| PCM | 60% aggregate | 55% | 55% |
| PCB | 60% aggregate | 55% | Not mandatory |
| PCMB | 65% aggregate | 60% | 60% |
* KV cutoffs are based on the 2024–25 KVS admission guidelines. Verify with your specific KV school for 2025–26 notification updates.
State Board Schools and the FYJC Portal
State board schools — particularly in Maharashtra (FYJC), Tamil Nadu, Karnataka, and Kerala — operate admission through centralised merit portals. Cutoffs here are set by seat availability and city-wise demand. In cities like Mumbai and Pune, FYJC Science stream cutoffs at reputed junior colleges have crossed 92% in recent years. In smaller cities and towns, 65–75% is often sufficient for government-aided colleges.
- Maharashtra: Apply through fyjc.org.in — merit is calculated on best-of-five or all-subject average depending on the college
- Tamil Nadu: Centralised counselling through the school education department portal
- Delhi: District-wise applications — Science cutoffs at popular government schools regularly exceed 85%
- Kerala: DHSE Plus One allotment via hscap.kerala.gov.in — Science stream is heavily competitive in all districts
A student who just meets the Science stream cutoff often carries subject gaps straight into Class 11. 62% in Maths at Class 10 means Physics and Physical Chemistry will feel steep from week one. At Angle Belearn, 1-to-1 academic support identifies exactly which Class 10 gaps carry forward — and closes them before the Class 11 curriculum accelerates.
Is 75% Enough for Science Stream?
75% is a functional Science stream aggregate for mid-tier CBSE, ICSE, and KV schools in most Indian cities. It will not open doors at top-ranked institutions in Mumbai, Delhi, Bangalore, or Hyderabad. But it is a real, workable number for a significant number of schools — provided your subject-level scores in Science and Maths are at 65% or above.
What 75% Aggregate Actually Means — Board by Board
- CBSE: 75% clears mid-tier school requirements in most cities. Top-tier schools in major metros will decline. Focus your shortlist on schools with 70–78% published cutoffs.
- ICSE: 75% is borderline. ICSE marking tends to be more stringent, so many admission committees account for this — but not all. Ask each school how they evaluate ICSE scores.
- KV: 75% comfortably clears the 60% aggregate guideline. Your child qualifies for Science stream at most KV schools at this percentage.
- State Boards (Maharashtra FYJC, Kerala HSCAP): 75% is strong for government-aided junior colleges outside major cities. In Mumbai and Pune, competitive Science stream seats at popular colleges may require 88%+.
The Post-2024 Percentage Calculation Shift
CBSE updated its grading and percentage calculation approach after 2024 — including changes to how internal assessment and board exam marks are combined. If your child’s school follows a moderation or internal assessment model that changed in 2024–25, the reported percentage may not be directly comparable to older admission cycles. Check whether your target school is comparing against the new or old grading norms. This is especially relevant for families whose children appeared in CBSE Class 10 in 2025. Our CBSE Class 10 Maths Standard Sample Paper 2025–26 guide also breaks down how the new exam pattern affects subject scores.
What Parents Should Do Right Now
Whether results are still pending or already published, there is a specific order of actions that keeps every option open. Follow these steps in sequence. Do not wait for one school to respond before contacting the next.
- Pull your child’s subject-wise marksheet. Do not rely on the overall percentage. Note the individual scores in Science and Mathematics separately.
- Shortlist 8 to 10 schools across three tiers — do not shortlist only top-tier schools. Include mid-tier and private unaided schools in your city.
- Call each school’s admission office directly and ask for three numbers: aggregate cutoff, Science minimum, and Maths minimum. Note who you spoke with and the date.
- Submit applications simultaneously to every school your child qualifies for on all three filters. Do not apply sequentially.
- If your child clears aggregate but not subject minimums, specifically target schools with no published subject minimum — these exist in every city.
- If no Science stream option is viable, explore Commerce stream with Science electives (Mathematics, Biology as additional subjects). This keeps engineering and medical options partially open.
- Once admitted, immediately address the subject gap that caused the low score. Class 11 Science is significantly harder. The gap from Class 10 does not close on its own. Learn how AI-powered 1-to-1 CBSE tuition targets concept gaps precisely — so your child is not just keeping up but building ahead.

Frequently Asked Questions
Q: What is the minimum percentage for Science stream after Class 10?
A: There is no single national minimum. Schools set their own cutoffs. Most mid-tier CBSE schools require 60–75% aggregate. Kendriya Vidyalayas generally require 60% aggregate with 55% in Science and Maths. Top schools in major cities require 85%+. Always ask for the subject-wise minimum — not just the aggregate — directly from each school’s admission office.
Q: What if my child gets less than 80% in Class 10 — is Science stream still possible?
A: Yes. Science stream admission below 80% is possible at mid-tier CBSE schools (70–79% range), most KV schools, private unaided schools, and government-aided colleges outside major metros. The key is your Science and Maths subject scores — if those are above the school’s subject minimum, the aggregate requirement is more flexible at many institutions.
Q: Do marks matter more than percentage for Science stream admission?
A: Subject-specific marks matter as much as — sometimes more than — aggregate percentage, especially for PCM stream. A student with 88% in Maths and 79% in Science but 76% overall may be preferred over a student with 80% aggregate but 60% in Maths, depending on the school’s internal policy. Always present your subject-wise marks alongside the aggregate when applying.
Q: Is 75% enough for Science stream admission in CBSE schools?
A: 75% is sufficient for mid-tier CBSE schools in most Indian cities, provided your child has 65%+ in Science and Maths subjects. It will not meet the cutoff at top-ranked CBSE schools in metros like Mumbai, Delhi, or Bengaluru, which typically require 85%+. For KV schools, 75% comfortably clears the 60% guideline cutoff.
Q: What should my child do if they miss the Science stream cutoff at their preferred school?
A: Apply to multiple schools simultaneously — do not wait for one rejection before trying the next. Specifically look for schools without subject-specific minimums. Check private unaided CBSE schools, state board junior colleges (FYJC / HSCAP portals), and schools in nearby areas. If no Science option works, explore Commerce stream with Mathematics as an additional subject — this preserves some engineering and finance pathway options.
Q: How are ICSE marks evaluated for Science stream admission to a CBSE Class 11 school?
A: CBSE schools receiving ICSE students typically look at the subject-wise marksheet rather than the ICSE aggregate alone. Some schools apply a conversion formula; others evaluate Maths and Science scores directly. There is no national standard — each school has its own cross-board evaluation policy. Always discuss this directly with the admission office before submitting your application.
