To pass WBBSE Madhyamik Supplementary 2026 Life Science, you need at least 27 marks out of 90 in the written paper.

The WBBSE Madhyamik Supplementary 2026 exam is scheduled from July 21 to July 28, 2026. Students who could not clear Life Science (Jeeban Bijnan) in the main Madhyamik exam can appear for this supplementary exam. The written paper carries 90 marks, and your internal assessment marks of 10 are carried forward from the main exam. Since many students are unsure how the 90-mark paper is structured, knowing your good attempts — the minimum questions you need to answer correctly in each group — gives you a clear and achievable target to clear the exam.

  • Minimum passing marks (written paper): 27 out of 90
  • Recommended safe score: 35 to 45 marks out of 90
  • Total paper marks: 90 written + 10 internal assessment (carried forward from main exam) = 100
  • No negative marking: Attempt every compulsory question without any risk of penalty
  • Supplementary exam schedule: July 21 to July 28, 2026

WBBSE Madhyamik Life Science 2026 Paper Pattern

The Life Science written paper for WBBSE Madhyamik Supplementary 2026 carries 90 marks and follows the same format as the main Madhyamik exam. It is divided into four groups — A, B, C, and D — covering MCQs, very short answers, short answers, and long answers. There is no negative marking in any group, which means every attempt carries only upside.

GroupQuestion TypeQuestions to AnswerMarks Per QuestionTotal Marks
AMultiple Choice (MCQ)15 (all compulsory)115
BVery Short Answer (VSA)21 out of 26121
CShort Answer (SA)12 out of 17224
DLong Answer (LA)6 out of 8530
Total Written Marks90

Group B (VSA) question types include one-word answers, fill in the blanks, true/false, and match-the-column items. Group D (LA) carries 5 marks each, which may be awarded as a whole or split as 3+2 or 2+3 sub-parts. You have 3 hours and 15 minutes to complete the paper.


Good Attempts for 27 Marks: Section-Wise Guide

A good attempt is any question you answer correctly or largely correctly. Since the passing mark is just 27 out of 90, you do not need to score well in every section. The table below shows the minimum good attempts needed to safely cross the 27-mark pass threshold along with the recommended target for a comfortable margin above the cutoff.

GroupMarks AvailableMinimum Correct Answers for 27-Mark PassExpected MarksRecommended Target
A — MCQ (1 mark each)158 to 9 correct out of 158–9 marks10–12 correct
B — VSA (1 mark each)2110 to 11 correct out of 2110–11 marks13–15 correct
C — SA (2 marks each)244 to 5 complete answers out of 128–10 marks5 to 6 complete answers
D — LA (5 marks each)301 complete + partial credit on 1 more6–8 marks2 complete answers
Minimum Combined Total32–38 marks38–46 marks (safe zone)

Since there is no negative marking, never leave an MCQ or VSA blank. Groups A and B together offer 36 marks in small-format questions — securing 19 to 22 marks from these two groups alone puts you within easy reach of the 27-mark pass mark. The remaining marks come from selective, well-chosen answers in Groups C and D.


Section-Wise Strategy to Clear Life Science Supplementary

Group A — MCQ (15 marks, all compulsory): Attempt every single MCQ without exception. If you are unsure, eliminate two unlikely options and guess from the remaining two. With even moderate preparation, targeting 9 to 10 correct answers gives you 9–10 marks from this section — a solid foundation before touching any other group.

Group B — VSA (21 marks, choose 21 out of 26): Skip the 5 questions that seem hardest and answer the remaining 21. Focus first on fill-in-the-blank and true/false items where partial recall is enough to score. Scoring 12 to 14 correct gives you 12–14 marks. At this point, combining Group A and Group B alone can yield 21 to 24 marks — just 3 to 6 marks short of passing.

Group C — SA (24 marks, choose 12 out of 17): Before writing, scan all 17 available short-answer questions. Select the 12 topics you feel most prepared for. Aim for 5 to 6 fully correct two-mark answers = 10–12 marks. Even partial answers earning 1 out of 2 marks on 3 to 4 additional questions can add 3–4 extra marks. Target: 10–12 marks from this section.

Group D — LA (30 marks, choose 6 out of 8): If your only goal is the passing mark, focus on 1 or 2 topics you know well and write complete answers for those. A single fully answered 5-mark question, combined with the marks from Groups A, B, and C, is often enough to clear 27. Do not skip Group D entirely — even partial credit of 3 out of 5 on two questions adds 6 marks and dramatically reduces pressure on the other groups.


Quick Tips for Good Attempts in Life Science Supplementary 2026

  • Start with Groups A and B: These two sections offer 36 marks through short-format questions. Clearing them early reserves your best concentration for Groups C and D.
  • Read before you write in Groups C and D: Spend 3 to 5 minutes scanning all question options before starting to write. Selecting familiar topics is worth more than answering in order.
  • Use labelled diagrams in Group D: Diagrams carry separate marks in Life Science long answers. A well-labelled diagram can earn marks even when your written explanation is incomplete.
  • No blank MCQs or VSAs: With zero negative marking in Groups A and B, any attempt is better than no attempt. Guess if you must.
  • Target 35 to 45 marks, not exactly 27: A buffer of 8 to 18 marks above the minimum protects you from partial-credit deductions in Group C and D and is the recommended safe zone.
  • Prioritise high-yield topics: Cell biology, genetics, evolution, photosynthesis, and human physiology are consistently high-weightage areas in Life Science based on previous year paper trends.

WBBSE Madhyamik Supplementary 2026 Life Science FAQs

Ques. What is the minimum passing mark for WBBSE Madhyamik Supplementary 2026 Life Science?

Ans. You need a minimum of 27 marks out of 90 in the written paper to pass WBBSE Madhyamik Supplementary 2026 Life Science. Your internal assessment marks of 10 are carried forward from the main exam and added to your written score for the final total.

Ques. How many MCQs must I answer correctly in Group A to help pass the exam?

Ans. Group A has 15 compulsory MCQs at 1 mark each. Getting at least 8 to 9 correct is the minimum recommended for your passing strategy. Since there is no negative marking, attempt all 15 questions without hesitation — even unsure answers can earn marks.

Ques. Can I pass WBBSE Madhyamik Supplementary Life Science without attempting Group D long answer questions?

Ans. It is technically possible only if you score very high in Groups A, B, and C. However, Group D carries 30 marks and even one fully answered 5-mark question significantly reduces pressure on other sections. Attempting at least 2 Group D questions is strongly recommended for all students targeting the 27-mark pass.

Ques. What is the recommended safe target score in WBBSE Madhyamik Supplementary Life Science?

Ans. While 27 is the minimum passing mark, targeting 35 to 45 marks out of 90 is considered the safe zone based on the paper’s marking pattern. This buffer protects against partial-credit situations in Group C and D and accounts for any marks lost to minor errors.

Ques. When is the WBBSE Madhyamik Supplementary 2026 Life Science exam?

Ans. The WBBSE Madhyamik Supplementary 2026 exam is scheduled from July 21 to July 28, 2026. Visit the official WBBSE website at wbbse.wb.gov.in for the subject-specific exam date and to download your admit card once it is released.

Ques. Is there negative marking in the WBBSE Madhyamik Life Science Supplementary 2026 exam?

Ans. No. There is no negative marking in any group of the WBBSE Madhyamik Supplementary 2026 Life Science paper. Wrong answers do not reduce your score in Group A, B, C, or D, so you should attempt every question rather than leave blanks.
