CBSE Board Exams 2027: Datesheet, Passing Marks and Exam Rules

Students preparing for the CBSE Class 10 and Class 12 board exams 2027 are waiting for the official datesheet. As of September 21, 2026, the Central Board of Secondary Education has not released the final timetable. Students should check cbse.gov.in for the official update.

Based on the schedule followed in past years, the datesheet may be released by the end of September or between October and November 2026. The official PDF will include exam dates, subject names, subject codes, exam timings and important instructions.

What the CBSE datesheet will include

The Class 10 and Class 12 timetable will help students plan their revision. It is expected to include:

• Date of each examination
• Subject name and subject code
• Exam start time and duration
• Instructions for the exam day
• Details about practical exams, where applicable

Do not depend on forwarded messages or screenshots on social media. A datesheet is useful only when it comes from the CBSE website. Rumours travel faster than school buses, but they are not always right.

How to download the CBSE datesheet 2027

1. Open the official website, cbse.gov.in.
2. Go to the section marked Latest @ CBSE or the examination section.
3. Find the link for the Class 10 or Class 12 datesheet 2027.
4. Open the PDF and check each subject date and timing.
5. Download the file and take a printout for easy reference.

Students should check the subject code along with the subject name. This small step can prevent confusion when two subjects have similar names.

CBSE board exam 2027 passing marks

Students must score at least 33 per cent to pass each subject. In subjects with theory and practical or internal assessment marks, students must meet the required pass rules for both parts as set by CBSE.

For many subjects, the total is divided into 80 marks for theory and 20 marks for practical work or internal assessment. Some Class 12 subjects, such as Physics, Chemistry, Biology, Geography and Computer Science, may have 70 theory marks and 30 practical marks. Students should check the latest syllabus and marking scheme issued by CBSE.

Two-exam system for CBSE Class 10

CBSE has announced a two-exam system for Class 10. The first examination will act as the main board exam. Students may get another chance to improve their marks or clear a subject through the second examination.

The exact schedule, rules and registration process will depend on the official CBSE notice. Students should wait for clear instructions from their school and the board before making plans for the second exam.

CBSE Class 10 grading system

CBSE uses a nine-point grading system for Class 10. The grades range from A1 to E. A1 is the highest grade, while E shows that the student needs to repeat the subject or meet the required standard.

Practical exam dates and preparation

CBSE usually conducts practical exams before the theory exams. For winter-bound schools, Class 12 practical exams may take place in November and December 2026. For other schools, practical exams are expected in January and February 2027.

Schools will share the exact practical schedule. Students should complete records, projects and lab files on time. They should also revise experiments, viva questions and key formulas. A missing file can create more stress than a difficult diagram.

What students should do while waiting

• Finish the syllabus as per the latest CBSE curriculum.
• Use sample papers and previous year question papers.
• Make a subject-wise revision plan.
• Check practical and internal assessment requirements with the school.
• Keep checking the official CBSE website for notices.
• Save the datesheet PDF once it is released.

Students can also use the datesheet to find study gaps between papers. Give more time to subjects that need practice, such as Mathematics, Physics and Accountancy. For theory-heavy subjects, revise key terms, maps, diagrams and answer formats.
