NEST Exam Pattern 2027: 80 Questions, 240 Marks, Marking Scheme and Paper Structure

NEST 2027 is a 3-hour computer-based test jointly conducted by NISER Bhubaneswar and UM-DAE CEBS, Mumbai for admission to 5-year Integrated MSc programmes in Basic Sciences. The exam has 80 multiple-choice questions for 240 marks across four subject sections: Biology, Chemistry, Mathematics, and Physics. Students can visit nestexam.in for the official 2027 notification and brochure once released.

• NEST 2027 is a 180-minute computer-based test with 80 questions for 240 marks across four science subjects.
• The exam has 4 sections: Biology, Chemistry, Mathematics, and Physics — each with 20 MCQs worth 60 marks.
• A correct answer earns +3 marks; a wrong answer deducts 1 mark; unanswered questions carry 0 marks.
• The merit list uses the best 3 out of 4 section scores — the weakest section is dropped automatically, capping the effective merit score at 180 marks.
• NEST 2027 is a single-session exam — your raw score is your final score with no normalisation applied.
• You must attempt at least 3 sections to be eligible for merit list consideration.
• PwD students receive 1 extra hour (total 4 hours) along with scribe facilities if required.

NEST Exam Pattern 2027: Overview

NEST 2027 follows a uniform CBT-based pattern with four equal-weight subject sections. The official 2027 brochure is expected in February 2027 at nestexam.in — until its release, the 2026 pattern serves as the primary reference. The table below captures all key exam parameters based on the most recent official information.

NEST 2027 is a 3-hour single-session computer-based test with 80 MCQs for 240 marks — your merit rank is calculated on the best 3 of 4 section scores, capped at 180 marks.

NEST Exam Pattern 2027: Important Dates

The NEST 2027 official notification is expected in the first week of February 2027 at nestexam.in. All dates below are tentative, based on the 2026 exam cycle timeline. Students should bookmark the official website for confirmed 2027 dates.

NEST 2027: Detailed Exam Pattern

The NEST 2027 paper has four equal sections — Biology, Chemistry, Mathematics, and Physics — each carrying 20 questions for 60 marks. All questions are single-correct MCQs. There is no per-section time limit; the full 3 hours is shared across all four sections and students can move freely between them.

Note: There is no per-section time limit in NEST 2027 — the 3 hours is shared across all four sections. You can navigate freely between them during the exam.

Note: The merit list uses the best 3 of 4 section scores. Attempting all four sections is strongly recommended so the system can automatically drop your lowest-scoring subject.

NEST Marking Scheme 2027

NEST 2027 uses a uniform +3/-1 marking scheme for all MCQs across all four sections. A wrong answer deducts 1 mark regardless of the subject. Unanswered questions carry no penalty.

Negative marking of 1 mark applies to all MCQs in NEST 2027 — avoid random guessing, especially in subjects where you are less confident.

There are no MSQ or numerical-type questions in NEST 2027 — the marking scheme is identical across all four sections. The +3/-1 rule applies to every one of the 80 questions.

NEST Subject-Wise Exam Pattern 2027

Each of the four NEST 2027 sections carries equal weightage — 20 questions for 60 marks. The exam does not publish per-topic question counts; questions are distributed across the broad topic areas within each subject based on the standard NEST syllabus at nestexam.in.

Biology

The Biology section tests conceptual understanding from cell biology through ecology. Genetics, molecular biology, and cell biology carry consistent high weightage in past NEST papers.

Chemistry

The Chemistry section covers physical, organic, and inorganic chemistry from the Class 11–12 syllabus. Numerical problems in physical chemistry and organic reaction mechanism questions appear consistently in NEST papers.

Mathematics

The Mathematics section spans calculus, algebra, coordinate geometry, and probability. Questions require multi-step reasoning; direct formula application rarely suffices in NEST.

Physics

The Physics section spans mechanics, modern physics, electromagnetism, and optics. Numerical application-based questions and conceptual MCQs both feature regularly across past NEST papers.

Note: Topic-wise question counts are not published officially. Refer to the NEST syllabus at nestexam.in for the complete list of topics within each subject.

NEST Question Types 2027

NEST 2027 features only single-correct MCQs across all four sections. The Multiple Select Question (MSQ) format was discontinued from NEST 2026 onwards — every question in the paper has exactly one correct answer from four options.

• Each question presents four answer choices; you must select exactly one option.
• You can mark a question for review and return to it later — the CBT interface supports flagging.
• The CBT interface allows free navigation between all four sections during the 3-hour window.
• There are no internal choices — every question must be attempted as presented.

NEST Exam Pattern: Changes in 2027 vs Previous Year

The NEST 2026 cycle introduced major structural changes from 2025 — the General section was removed, MSQs were eliminated, and subject-section marks were revised. The official 2027 brochure has not yet been released (expected February 2027). Based on current information, the 2027 pattern is expected to remain the same as 2026. The table below compares the three most recent cycles.

The NEST 2026 pattern introduced significant changes — the General section was removed, MSQs were eliminated, and each subject section now carries 20 questions at +3 marks each — plan your 2027 preparation based on this revised structure.

How to Prepare Based on NEST Exam Pattern

NEST 2027 preparation must be pattern-aligned. The four equal-weight sections mean you cannot afford to neglect any subject, yet the best-3-of-4 merit formula rewards strategic depth in your strongest subjects.

1. Attempt all 4 sections: Even though only the best 3 count toward merit, attempting all four gives the system the data to drop your weakest — never skip a section voluntarily.
2. Build depth in your top 3 subjects first: A high score in three subjects has a greater merit impact than a spread-out moderate effort in all four. Identify your strongest three subjects early and prioritise them.
3. Apply the +3/-1 logic before every attempt: Attempt a question only when you can eliminate at least 2 of the 4 options. Guessing incorrectly on 10 questions costs you 10 marks plus the +3 you missed — a 40-mark swing.
4. Self-pace with roughly 45 minutes per section: No per-section timer exists in NEST 2027. Allocating 45 minutes per subject keeps you on track and leaves review time within the 3-hour window.
5. Revise Class XI and XII NCERT concepts thoroughly: NEST questions test conceptual depth, not surface familiarity. A thorough understanding of standard Class 11–12 board-level topics in all four subjects is the foundation.
6. Practice full 3-hour mock tests regularly: NEST is a single sitting with no normalisation — your raw score is final. Build stamina and time discipline by simulating the full paper under timed conditions.
7. Solve NEST previous year papers: Past papers from 2007–2025 reveal recurring question styles, difficulty levels, and high-weightage topics within each section — and are the most direct preparation resource available.
