The West Bengal Class 12 Higher Secondary examinations have introduced an important change this year. For the first time, students appearing for the Semester III Higher Secondary examination are using OMR sheets to answer multiple-choice questions (MCQs).
The change is being implemented by the West Bengal Council of Higher Secondary Education (WBCHSE) and affects more than 7 lakh registered candidates across the state. The Semester III examination began on September 21, 2026, as part of the Higher Secondary examination cycle for 2027.
What Has Changed in the West Bengal Class 12 Exam?
The biggest change is the introduction of OMR (Optical Mark Recognition) answer sheets for Semester III.
Unlike conventional answer scripts, OMR sheets are designed to be processed electronically. Students mark their selected answers against the questions, allowing the responses to be scanned and evaluated using OMR technology.
The Semester III examination is based on multiple-choice questions, making OMR sheets suitable for recording students’ answers. WBCHSE has also published a specimen OMR sheet and instructions to help students become familiar with the new format.
More Than 7 Lakh Students Affected
The introduction of OMR sheets is significant because of the large number of students appearing for the examination.
According to reports, 7,18,620 candidates are participating in the Semester III Higher Secondary examination. The candidates include 3,15,731 boys and 4,02,889 girls, with examinations being conducted across thousands of schools in West Bengal.
This makes the new OMR-based examination system one of the major changes students need to understand during the current Higher Secondary examination cycle.
Why Are OMR Sheets Being Used?
OMR technology allows marked responses to be scanned and processed electronically. Since Semester III examinations are based on MCQs, the format can be used to record answers in a standardized manner.
However, WBCHSE’s official materials focus on helping schools and students become familiar with the OMR format rather than describing the introduction as a change in the syllabus itself.
The Council had already issued a specimen OMR sheet for Semester III and asked institutions to familiarise students with its use before the examination.
Students Need to Be Careful While Marking Answers
For students, the change means that answering an MCQ is not only about choosing the correct option. They also need to follow the instructions on the OMR sheet carefully.
Students should read the instructions provided by WBCHSE and their school before the examination. The Council has specifically provided a specimen OMR sheet so that students can understand the format beforehand.
This is particularly important because OMR-based examinations depend on accurately recording the selected option.
Strict Examination Security Measures
The introduction of OMR sheets comes alongside tighter security arrangements for the Semester III examinations.
According to reports, question papers have unique serial numbers and sealed packets are opened in front of students before distribution. Two students are required to verify the seal-opening process.
The Council has also arranged security measures including CCTV surveillance and metal-detector checks at examination centres. Electronic devices such as mobile phones are prohibited inside examination halls.
The used OMR sheets are also being collected through India Post and transported to regional offices, according to the Council’s examination arrangements.
What Is the West Bengal HS Semester System?
The OMR change is part of the broader semester-based Higher Secondary examination structure introduced by WBCHSE.
For Class 12, Semester III is followed by Semester IV. The Council’s annual working plan lists Semester III examination results for publication by November 2026, while Semester IV examinations are scheduled separately.
The Semester III examination includes MCQ-based papers, which is why the OMR format is particularly relevant to this stage of the examination system.
When Are the Semester III Exams Being Held?
The Semester III examinations began on September 21, 2026.
The original schedule covered examinations through October 7, but WBCHSE subsequently revised dates for examinations that were affected by a scheduled by-election. The exams originally planned for October 5, 6 and 7 were shifted to October 12, 13 and 14.
Students should therefore rely on the latest timetable issued by WBCHSE rather than older schedules circulating online.
What Should Students Remember About the OMR Exam?
Students appearing for the West Bengal Class 12 Semester III examination should keep a few things in mind:
- Understand the OMR sheet format before the examination.
- Read all instructions carefully.
- Practise MCQs using an OMR-style format if possible.
- Follow the instructions provided by the school and WBCHSE.
- Check the latest examination timetable before each paper.
- Reach the examination centre on time.
- Do not carry prohibited electronic devices into the examination hall.
The Council has made the specimen OMR sheet available so students and institutions can become familiar with the format before or during the examination process.
Final Takeaway
The introduction of OMR sheets in the West Bengal Class 12 Semester III examination marks a significant change for Higher Secondary students. With more than 7.18 lakh candidates appearing, the new system affects a large student population across the state.
For students, the key is to understand that Semester III uses MCQ-based examinations and OMR answer sheets, making familiarity with the new answer format important.
As the West Bengal Higher Secondary system continues under the semester structure, students should follow official WBCHSE notifications, specimen materials and revised examination schedules for the latest information.
