CBSE Class 10 Boards 2027: What's Changed and a Calm 4-Month Revision Plan
The CBSE Class 10 board exams for 2027 are expected to start in February 2027, with an optional second exam in May for students who want to improve their marks. That leaves about 100 days, enough for a calm plan without last-minute panic, as long as you start this month.
This guide covers what has changed, how the marks are made up, and a month-by-month plan that starts with finding your own weak chapters, not re-reading the whole textbook.
What's new: two board exams a year
From 2026, CBSE holds two board exams for Class 10 each year. Here is how it works:
- The first exam is compulsory for everyone. It is held from mid-February. CBSE's notification says: "It is mandatory for all the students to appear in the first Board examination."
- The second exam in May is optional. Students who have passed can try to improve their marks in up to three subjects from Science, Mathematics, Social Science and languages. Students placed in compartment can also take it.
- Both exams cover the full syllabus. You can't drop chapters for the second attempt.
- Practicals and internal assessment happen only once, before the first exam.
- Results: the first exam's results come out around April, and the second exam's around June.
- Missing the first exam is costly. A student absent in three or more subjects can't take the May exam and must wait until the following February.
The 2027 date sheet had not been released when this article was written (early November 2026). Check cbse.gov.in for the final dates.
What this means for you: treat February as the real exam. The May exam is a safety net for one or two subjects, not a second chance to prepare everything.
How the marks are made up
In the main subjects (Maths, Science and Social Science), the board paper is usually out of 80 marks and internal assessment out of 20. You need at least 33% in each subject to pass.
CBSE has said the question paper design will not change for the 2026–27 session. Exam guides summarising the latest sample papers describe the theory paper like this:
- Competency-based questions, about 50%: using a concept in a new situation, such as case studies, data and real-life problems.
- Multiple choice questions (MCQs), about 20%: quick recall and understanding.
- Short and long answers, about 30%: writing steps, reasons and explanations.
Half the paper asks students to apply ideas, not repeat them. A student who memorised "refraction is the bending of light" but has never seen why a pencil looks bent in water will lose marks in the competency section. Understanding beats memorising.
Check your school's subject scheme and CBSE's sample question papers for the exact split in each subject.
A November-to-February revision plan
- November, find the gaps: take one full, timed Class 10 assessment per subject on New Age Learning. The report shows your score in each chapter. Mark each chapter Strong, OK or Weak, and finish any chapter school hasn't covered properly.
- December, fix the weak chapters: work through the Weak chapters first, at least 10 questions each, with solutions. Add a few competency-based questions from CBSE's sample papers every week.
- January, practise full papers: one timed paper per main subject each week, from CBSE sample papers, previous years' papers, or a timed New Age Learning assessment (a fresh mix of questions every attempt). After each one, write down every mark you lost and why. Get practical files and projects done.
- February, revise lightly: go over your own notes, formula sheets and the mistakes list. No new topics. Sleep 7–8 hours, especially the night before a paper.
A simple daily rhythm: one 45-minute block on a weak chapter, one 30-minute block of mixed practice from chapters you've already done, and 10 minutes going over yesterday's mistakes. Mixing old questions into new practice helps you pick the right method in the exam.
Find your weak chapters, then get the right help
Most lost marks come from a few chapters, not the whole syllabus. The fastest way to find them is a short test on each chapter, not re-reading.
- Take a full Class 10 assessment. New Age Learning's free Assessments section has timed Class 10 papers in Maths, Science and Social Science. Each one is marked as soon as you submit, with an explanation for every answer and a chapter-wise report that shows which chapters pull your score down.
- Practise the weak chapters one by one. The chapter-wise Class 10 practice pages have solved questions and a short test for every chapter.
- Read the explanation for every wrong answer. It shows why you went wrong: a concept, a careless step, or a formula.
- Rebuild the concept, not just the answer. For ideas that feel abstract (refraction, electric circuits, trigonometry), an interactive lab lets you see the idea work before you practise it again.
- Take your list of weak chapters to your teacher or tutor. A clear list ("Chapter 10, refraction; Chapter 8, trigonometry identities") makes their help much more targeted.
- Retake the assessment after a week. Each attempt gives a fresh mix of questions, so you practise the idea instead of memorising answers. If a chapter's score goes up, move on. If not, ask for help with that chapter again.
The test doesn't replace your teacher. It tells you and your teacher exactly where to spend the next 100 days.
For parents: how to help without adding pressure
- Ask about chapters, not marks. "Which chapter felt hard this week?" opens a conversation; "How much did you score?" usually closes it.
- Protect sleep and meals. Tired students make careless mistakes, especially in maths.
- Help plan, not police. Sit together once a week to look at the weak-chapter list and the plan for the next 7 days.
- Keep the May exam in perspective. It's a useful safety net, but saying "you can always do it again in May" can make February feel less important.
- Watch for signs of stress: trouble sleeping, skipping meals, or avoiding study altogether. Talk to the class teacher or school counsellor early. CBSE also runs a free counselling helpline during exam season.

Is the second CBSE Class 10 board exam compulsory?
No. The first exam (February) is compulsory. The second exam (May) is optional and lets you improve up to three subjects from Science, Mathematics, Social Science and languages.
Is the syllabus smaller for the second exam?
No. Both exams cover the full syllabus.
How many marks do I need to pass Class 10?
At least 33% in each subject.
What are competency-based questions?
Questions that ask you to apply a concept to a new situation, such as a case study, a graph or a real-life problem. They make up about half the theory paper.
How should I start revising for the Class 10 boards?
Start with a short test on every chapter to find your weak ones, fix those first with your teacher, a lab or practice questions, and do full timed papers in January.
Where can I take free Class 10 mock tests online?
New Age Learning's Assessments section has free, timed Class 10 papers in Maths, Science and Social Science. They are marked instantly, with explanations and a chapter-wise report. Use them alongside CBSE's official sample papers.
