NEST Exam Pattern 2026: Revised Pattern, Marking Scheme and Section Wise Weightage

NEST 2026 (National Entrance Screening Test) is a 3-hour computer-based test jointly conducted by NISER Bhubaneswar and UM-DAE CEBS Mumbai for admission to their integrated science degree programmes. The exam is held on June 6, 2026 in a single afternoon shift from 2:00 PM to 5:00 PM. It covers four subject sections — Biology, Chemistry, Mathematics, and Physics — for a total of 240 marks, with your merit rank computed on the best three section scores (maximum 180 marks).

• NEST 2026 is a 3-hour computer-based test with 80 questions for 240 marks across four subjects.
• The exam has 4 sections — Biology, Chemistry, Mathematics, and Physics — each with 20 MCQs carrying 60 marks.
• A correct answer earns +3 marks; a wrong answer deducts 1 mark; leaving a question blank gives 0 marks.
• Merit ranks at NISER and UM-DAE CEBS are based on the best 3 out of 4 section scores — your weakest section is dropped, capping the effective merit score at 180 marks.
• You must attempt at least 3 sections to appear in the merit list; attempting all 4 gives you the flexibility to drop your weakest section automatically.
• The General section has been removed in 2026 and the exam duration is cut from 3.5 hours to 3 hours — the biggest structural change from the 2025 pattern.
• NEST 2026 is a single-shift exam — no second session, no normalisation — so your raw score is your final score.

NEST Exam Pattern 2026: Overview

NEST 2026 is a Computer-Based Test (CBT) conducted in a single afternoon session on June 6, 2026. The exam has four subject sections — Biology, Chemistry, Mathematics, and Physics — each containing 20 MCQs for a total of 80 questions and 240 marks. Since the exam runs in a single nationwide shift, no score normalisation is applied — your raw score is used directly for merit ranking.

NEST 2026 is a 3-hour computer-based test with 80 questions for 240 marks — and your rank at NISER and UM-DAE CEBS is determined on a merit score of 180 marks (best 3 sections).

NEST Exam Pattern 2026: Important Dates

The table below covers all key NEST 2026 milestones. Upcoming events are shown first in order of occurrence; completed events follow in chronological order. With the exam conducted on June 6, 2026, the next milestones are the provisional answer key (June 10–12) and the final result (June 24).

NEST 2026: Detailed Exam Pattern

The NEST 2026 question paper has four sections, each devoted to one subject. Every section carries 20 MCQ questions worth 3 marks each, adding up to 60 marks per section and 240 marks overall. Each MCQ has four options with exactly one correct answer; no partial credit is awarded for any section.

You can attempt all four sections, but only your best three section scores count towards your rank at NISER and UM-DAE CEBS.

Note: There is no per-section time limit in NEST 2026. You can navigate freely between all four sections during the 3-hour window and allocate your own time per subject. The Duration column shows "–" per section because the full 180 minutes is shared across all four sections.

Note: The merit list for both NISER Bhubaneswar and UM-DAE CEBS Mumbai is prepared on the basis of the best three scores out of four. The section with the lowest score is automatically excluded. The maximum effective merit score is therefore 180 marks, not 240.

NEST Marking Scheme 2026

NEST 2026 uses a uniform marking scheme across all four sections. Every question is an MCQ with a single correct answer. Correct responses earn +3 marks, wrong responses lose 1 mark, and unattempted questions receive 0 marks. There are no MSQ (multiple select) or numerical-type questions in 2026 — the format is entirely objective MCQ, removing the dual marking scheme of 2025.

Negative marking of 1 mark applies to every wrong MCQ answer in NEST 2026 — avoid guessing randomly, especially in your weaker subjects.

Since merit is based on best 3 sections, consider your subject strengths before deciding how aggressively to attempt each section. A net score close to zero in your fourth section still qualifies — that section can be the dropped one. Focus on accuracy in your three strongest subjects and avoid penalty-driven losses in those sections.

NEST Subject-Wise Exam Pattern 2026

Each of the four NEST 2026 sections draws questions from the Class 11 and 12 syllabus of the respective subject, broadly aligned with NCERT/CBSE standards but extended to higher-order and application-level questions. The tables below show the subject-wise breakdown and key topic areas for each of the four sections.

Biology (Section 1)

The Biology section tests your understanding of life sciences from cell level to ecology. Questions often require applying concepts rather than direct recall, with genetics and molecular biology carrying consistent high weightage in past NEST papers.

Chemistry (Section 2)

The Chemistry section covers physical, organic, and inorganic chemistry from the Class 11–12 syllabus. Numerical problems in physical chemistry are common, and organic reaction mechanisms require deep conceptual understanding.

Mathematics (Section 3)

The Mathematics section includes calculus, algebra, coordinate geometry, and probability. Questions are conceptual and often require multi-step reasoning; direct formula application alone is rarely sufficient.

Physics (Section 4)

The Physics section spans mechanics, modern physics, electromagnetism, and optics. Numerical and application-based questions make up the majority; conceptual one-liners and derivation-based MCQs also appear regularly.

Note: Topic-wise question counts are indicative and based on previous year NEST papers (2007–2025). Exact distribution varies each year. You should cover all topics listed in the official NEST syllabus available at nestexam.in.

NEST Question Types 2026

NEST 2026 uses only one question type across all four sections: MCQ (Multiple Choice Question) with a single correct answer. Each MCQ presents four options (A, B, C, D) and exactly one option is correct. This is a notable simplification from 2025, which included MSQs (multiple select questions) requiring you to identify all correct answers from four options.

Key points about the MCQ format in NEST 2026:

• 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 questions.
• There are no numerical / integer-type questions in NEST 2026 — all 80 questions are MCQ.
• There are no MSQ (multiple select questions) in NEST 2026 — a significant change from the 2025 pattern.
• Questions do not have internal choices — every question must be attempted as presented.
• The CBT interface allows free navigation between sections — you are not locked into one section at a time.

NEST Exam Pattern: Changes in 2026 vs Previous Year

NEST 2026 introduces significant structural changes compared to the 2025 pattern. The General section has been removed, the duration has been reduced by 30 minutes, and the question format has been simplified from MCQ+MSQ to MCQ-only. While the maximum merit score stays at 180 marks, the way it is calculated is different from 2025.

The NEST pattern has changed substantially in 2026: the General section is removed, duration is cut to 3 hours, and MSQs are dropped — plan your preparation strategy accordingly.

How to Prepare Based on NEST Exam Pattern

Your preparation strategy for NEST 2026 should directly reflect the 4-section MCQ structure, the best-3-of-4 merit rule, and the –1 negative marking system. Use the pattern to build a targeted plan rather than treating all four subjects equally.

1. Identify your three strongest subjects early and maximise your score in those. Since only the best 3 section scores count for merit, your rank is determined by your top three performances. Students from a PCM background should target Physics, Chemistry, and Mathematics. Students from PCB should prioritise Biology, Chemistry, and their third science.
2. Attempt all four sections — but allocate time strategically. The 3-hour window has no per-section time limit. Target roughly 40–45 minutes per section and keep 10–15 minutes at the end for review. Attempting all four sections lets the system drop your worst section automatically.
3. Apply strict negative-marking discipline throughout. A wrong answer costs you 1 mark and denies the +3 you could have earned — a 4-mark swing per question. Attempt only when you can eliminate at least two options. Random guessing is a net loss over any significant number of questions.
4. Solve NEST previous year papers from 2007–2025, available for free at nestexam.in. NEST questions are known for conceptual depth and novel application. Past papers reveal the question style, difficulty level, and which topic areas recur most often within each section.
5. Build your foundation on NCERT Class 11 and 12 textbooks for all four subjects. NEST does not go beyond the Class 12 scope, but it tests concepts at an application level. A thorough NCERT foundation is essential before moving to advanced reference material.
6. Practice timed sectional mocks — aim to complete 20 questions in 40 minutes per section. Without per-section limits, students often over-invest time in a favourite subject and rush the rest. Timed drills reveal which topics slow you down and build discipline for exam day.
7. For Biology, prioritise genetics, molecular biology, and cell biology above other areas. These topics carry high question density in NEST papers, require both conceptual clarity and mechanistic recall, and are the areas where high-scoring students typically separate themselves.
