Key Changes in the Final Answer Key
After reviewing the challenges, the council has made special decisions on more than 40 questions across subjects:
| Type of Change | Examples |
|---|---|
| “No correct option” | English A (Q26), Chemistry (Q29), Biological Sciences (Q26) |
| All four options accepted (A, B, C, D) | Accountancy (Q15, 33, 35, 36), Sociology (Q18, 21, 27), Education (Q11, 38), Computer Science/Text (Q24, 27, 36), Sanskrit (Q7), Nutrition (Q23), Social Work (Q2, 35) and others |

Question numbers above refer to Set A. Use the B, C and D columns to find the matching question in your set.
What this means: Where more than one option is accepted, students who marked any of the accepted options will usually get the marks. How WBCHSE will award marks for “No correct option” questions (for example, bonus marks for all students) is not stated in the key PDF, so check the council’s official notice.

- For each question, find the matching row in the final key using your set’s column.
- Count the questions where your answer matches the key, including any question where multiple options are accepted.
- Multiply by the marks per question for your subject, as given in the WBCHSE semester scheme.
Example: A Physics paper has 35 questions. If you got 30 correct according to the final key, your Semester III MCQ score is 30 × (marks per question for Physics).
Your final HS 2027 result will combine the Semester III (MCQ) and Semester IV (descriptive) marks, along with practical or project marks where applicable.
Understanding the WBCHSE Semester System
Under the new semester system, Class 12 students in West Bengal take:
