In short: Maharashtra Board HSC Science 2027 exams run from February 8 to March 16, 2027. Physics, Chemistry, and Biology carry 70 marks theory + 30 marks practical each. Maths carries 80 marks theory + 20 marks internal. English is 80 marks theory + 20 marks internal. This guide provides the exact unit-wise marks distribution for every subject, highlights MHT-CET overlap chapters, and gives a strategy for scoring 85%+ across your Science stream.
The Maharashtra State Board HSC Science exam is the gateway for over 5 lakh students each year — not just to college admissions, but also to MHT-CET, JEE Main, and NEET. The unique challenge for Maharashtra Science students is that the Balbharati syllabus overlaps significantly with competitive exam content but uses different terminology and problem styles. Understanding the board exam weightage lets you prepare for both simultaneously.
This guide covers Physics, Chemistry, Mathematics, Biology, and English — with detailed marks allocation so you can plan every study hour strategically.

MHT-CET Overlap with HSC Syllabus
This table shows how much of each HSC subject's syllabus directly overlaps with MHT-CET, helping you prepare for both exams simultaneously.
| Subject | HSC Marks | MHT-CET Weightage | Overlap % | Key Overlap Chapters |
|---|---|---|---|---|
| Physics | 70 | 100 marks (50 Qs) | ~85% | Electrostatics, EM Induction, Optics, Semiconductors |
| Chemistry | 70 | 100 marks (50 Qs) | ~85% | Electrochemistry, p-Block, Organic Reactions |
| Maths | 80 | 100 marks (50 Qs) | ~80% | Integration, Differentiation, Probability, 3D Geometry |
| Biology | 70 | 100 marks (50 Qs) | ~90% | Genetics, Reproduction, Biotechnology, Ecology |
Strategy note: Since the MHT-CET syllabus is drawn almost entirely from the HSC syllabus (plus some Class 11 topics), a strong board exam preparation automatically covers 80-90% of MHT-CET. Focus on board-style answers for February-March, then shift to MCQ practice for MHT-CET in April.
Practical Exam Overview (February 2027)
| Subject | Practical Marks | Duration | Key Components |
|---|---|---|---|
| Physics | 30 | 3 hours | 2 experiments + viva + journal |
| Chemistry | 30 | 3 hours | Salt analysis + volumetric + viva |
| Biology | 30 | 3 hours | Spotting + experiment + viva |
| Maths | 20 (Internal) | School-based | Project + journal + class test |
Practical exams are typically held in the first two weeks of February, before the theory exams begin. Most students score 22-28 out of 30 in practicals. Keep your journal neat and complete throughout the year — journals carry 4 marks in every Science practical.
Strategy for Scoring 85%+ in HSC Science
| Phase | Timeline | Focus |
|---|---|---|
| Phase 1 | October–November 2026 | Complete syllabus revision, NCERT cross-reference for NEET |
| Phase 2 | December 2026 | Solve 3 previous year papers per subject |
| Phase 3 | January 2027 | Weekly mock tests, formula sheets, diagram practice |
| Phase 4 | Feb 1–7 | Practical exam preparation and viva revision |
| Phase 5 | Feb 8 – Mar 16 | Theory exam period — revise next-day subject |
| Phase 6 | After March 16 | Shift fully to MHT-CET / JEE / NEET MCQ practice |
Frequently Asked Questions
What is the passing criteria for Maharashtra HSC Science 2027?
You need 35% overall in each subject (theory + practical combined). For Science subjects with 70+30 split, that means roughly 23-24 marks in theory if you score well in practicals. However, aiming for just passing marks is risky — target at least 50% per subject for comfortable passing and 70%+ for competitive exam eligibility.
How do Maharashtra HSC marks affect MHT-CET admission?
MHT-CET 2027 admission uses a composite score where board exam marks carry significant weightage alongside CET scores for most engineering and pharmacy colleges. A higher HSC percentage directly improves your CET merit rank. For medical admissions through NEET, board marks matter for eligibility (50% for General, 40% for OBC/SC/ST) but not for ranking.
Should I study from NCERT or Balbharati for HSC board exams?
For HSC board exams, study exclusively from Balbharati textbooks — the exam is set from these books. However, if you are also preparing for NEET, cross-reference Balbharati Biology chapters with NCERT because NEET questions are based on NCERT language. For MHT-CET, Balbharati is sufficient since CET is based on the Maharashtra syllabus.
Which are the most difficult chapters in HSC Physics?
Students typically find Electromagnetic Induction, AC Circuits, and Wave Optics the most challenging. However, these are also the highest-scoring chapters once you understand the derivations. Start with Electrostatics and Current Electricity (more intuitive), then move to EM Induction. Practice derivations daily — Maharashtra Board Physics is derivation-heavy.
How should I manage board exams and competitive exams (JEE/NEET) together?
From October to February, focus primarily on board exam preparation using Balbharati. The board syllabus covers 80-85% of competitive exam content. After your board exams end (March 16), you have about 6-8 weeks before MHT-CET and 2-3 months before JEE/NEET. Use this gap exclusively for MCQ practice and NCERT revision. Read our detailed guide on preparing for boards and competitive exams together.
What practical experiments should I focus on for maximum marks?
For Physics, focus on experiments involving Ohm's Law, meter bridge, and sonometer — these are the most commonly examined. For Chemistry, master salt analysis systematically (group-by-group) and practice volumetric calculations. For Biology, diagram-based spotting is key — label everything clearly. Keep journals updated throughout the year.
