Why Was the WB HS Routine Revised?
The Council revised the October 5, 6 and 7 examination dates in view of bye-elections scheduled for October 6 in the Nandigram and Rejinagar Assembly constituencies.
Students should use this reason only as context; the important operational change is that the three affected papers now fall on October 12, 13 and 14.
WB HS Semester III Exam Timing
The affected October 12, 13 and 14 examinations are scheduled from 11:00 AM to 12:30 PM.
Students should follow the subject-specific duration printed in the current routine and admit-card instructions because certain subjects can have different prescribed durations.
Is the Entire WB HS Routine Changed?
No. The September 10 notification is a partial revision.
The key change concerns the three dates:
- October 5.
- October 6.
- October 7.
Students should not assume that every earlier exam date has been postponed.
Why Is It Called HS Examination 2027 If It Is Held in 2026?
This is a common source of confusion.
The examination belongs to the Higher Secondary 2027 academic/examination cycle, but Semester III is conducted in 2026 under the semester system.
Therefore, searches such as “WB HS Semester 3 exam 2026” and “WB HS Semester 3 exam 2027” can refer to the same Semester III examination cycle.
WBCHSE Semester System Explained
Under the semester framework, Higher Secondary studies are divided into semester stages rather than being based entirely on one final annual examination.
For Class 12, Semester III and Semester IV form key examination stages.
Semester III vs Semester IV
| Semester III | Semester IV |
|---|---|
| Conducted during the earlier part of Class 12 examination cycle | Later Class 12 semester examination |
| 2027 cycle Semester III begins in September 2026 | Conducted later according to the Council's schedule |
| Uses the applicable Semester III pattern | Uses the applicable Semester IV pattern |
WB HS Semester III Question Pattern
Semester III is structured around the Council's applicable objective/MCQ framework.
Students should prepare specifically for objective questions rather than studying as though every answer will require a traditional long descriptive response.
WB HS Semester III OMR Sheet
The Council has issued information concerning the OMR answer sheet used for Semester III.
Students should practice:
- Reading question numbers carefully.
- Marking the intended response correctly.
- Avoiding unnecessary marks on the OMR sheet.

- Marking the wrong question number.
- Using an unauthorized writing instrument.
- Making stray marks.
- Damaging the sheet.
- Ignoring candidate-information instructions.

WB HS Semester III Admit Card
Students must carry the applicable admit card according to Council and school instructions.
Check:
- Student name.
- Registration details.
- Subjects.
- Examination center.
- Other printed instructions.
What If My Admit Card Shows the Old Date?
Where an examination has subsequently been officially rescheduled, students should follow the latest Council notification and instructions communicated through their institution.
Do not appear at the examination center on the old October 5, 6 or 7 date for the affected papers merely because an older copy of the routine is still circulating online.
WB HS Semester III Pass Criteria
WBCHSE's current semester-system guidance states that a student has to secure 30% in the five mandatory subjects — two language subjects and three elective subjects — with theory and project/practical requirements satisfied independently as applicable.
