CBSE Class 12 Board Exam 2027 — Pattern, Official Dates and a Study Plan

CBSE Class 12 marks matter for college admissions and, in many courses, for entrance-based admissions too. The good news is that the board exam follows the NCERT textbooks and the CBSE sample papers closely, so steady, well-planned preparation works.

This guide explains the paper pattern, the official 2027 dates, the pass rules and a month-by-month plan. CBSE released the 2027 date sheet on 6 November 2026: the exams start on 16 February 2027.

When to expect the 2027 exams

In 2026 the CBSE board exams began on 17 February 2026, and the Class 12 papers ran into early April.
For 2027, the theory exams start on 16 February 2027 (Physics) and end on 9 April, with every paper at 10:30 am IST, according to CBSE’s official date sheet of 6 November 2026. See our CBSE date sheet 2027 guide for the main subject dates. Practical exams, projects and internal assessment are scheduled from 1 January 2027 for schools in India and abroad (winter-bound schools: 9 November to 19 December 2026), according to CBSE’s circular of 5 November 2026.
The two board exams a year system introduced in 2026 is for Class 10 only. Class 12 has one main board exam, with a supplementary exam for students who need it.

How the papers are set

Most theory papers are 3 hours long. Recent papers had about half the marks from competency-based questions (case studies, source-based and application questions), with the rest from multiple-choice and short and long answer questions.
Marks are split between theory and practical or internal assessment. For example, Mathematics has an 80-mark theory paper with 20 internal marks, and Physics has a 70-mark theory paper with a 30-mark practical.
To pass, you need at least 33% in the theory paper and in the practical/internal part separately, wherever both apply.
The official syllabus, marking scheme and sample question papers for each subject are on cbseacademic.nic.in.

Preparing for competency-based questions

Read the NCERT textbook line by line; case-study passages are built on its concepts and examples.
Practise application questions: after each chapter, ask yourself how the idea would apply to a real situation, a graph or a data table.
Solve the CBSE sample papers and their marking schemes; they show exactly how answers are marked.

A study plan until the board exam

November–December: finish the syllabus with your school, then start a first revision. Note weak chapters.
December–January: pre-board exams and practicals. Treat the pre-board as a full rehearsal and fix every mistake.
January–February: one sample paper per subject every few days under time, and short daily revision of formulas, diagrams and key terms.
Between papers: CBSE leaves gaps between many papers; use them for final revision of that subject only.

For students in the Gulf and Kerala

CBSE exams are held on the same schedule in India and abroad, so Gulf students follow the same date sheet. Check your exam centre and timings with your school.
If you are also preparing for entrance exams such as NEET, JEE, KEAM or CUET, study each chapter for the board first, then practise entrance-style questions on it.
