The change in one sentence
From the 2027 session, CBSE holds the Class 10 board examination in two sittings in the same year. The first sitting, expected in February–March 2027, is compulsory for everyone. The second sitting, tentatively in May–June 2027, is optional and exists so a student can improve marks, clear a compartment, or sit a paper they missed. Class 12 is unaffected and still has one annual exam. The idea, drawn from the National Education Policy 2020, is to take some of the "one exam decides everything" pressure off Class 10 and give a genuine second chance.
What has not changed: the exam itself
It helps to be clear about this first, because it is the part that matters for daily study. The paper, the syllabus and the marking scheme are the same as recent years.
Each main subject is out of 100 — an 80-mark theory paper of three hours, plus 20 marks of internal assessment marked by your school.
You need 33% overall in a subject to pass it.
The 20 internal marks are split into four parts of 5 each: periodic tests (usually best of two), multiple assessments such as quizzes and oral tests, a portfolio of classwork and assignments, and subject enrichment — practical work in Science, lab activities in Maths, listening and speaking in the languages, project work in Social Science.
In recent sample papers, roughly half the theory paper is competency-based — case studies, source-based sets, assertion–reason and application MCQs — about a fifth is straight objective or MCQ type, and the remaining portion is short and long written answers.
None of that is different in 2027. If you were preparing for a normal Class 10 board exam, keep preparing for exactly that. Always cross-check the question split against the official CBSE sample paper for your year on cbseacademic.nic.in, since the Board revises it from time to time.
Exam 1: the one everybody sits
The February–March exam is the real board exam. Every registered Class 10 student appears for it, across all subjects, on the full syllabus. If your result here is one you are happy with, you do nothing more — those marks become your final result and you move on to Class 11 admissions with them. Treat this exam exactly the way students have always treated the Class 10 boards: it is the one that counts, and the second sitting is insurance, not a retake you have already booked.
Exam 2: who it is actually for
The May–June exam is optional, and it now does the job that three separate things used to do. It is for a student who passed comfortably but wants a higher score in a few subjects. It is for a student placed in compartment in one or two subjects, who earlier would have waited for a separate supplementary exam. And it is for a student who was absent for a paper in the first sitting. The old standalone compartment or supplementary exam has been merged into this one.
If you are improving your score, you may reappear in up to three subjects out of Mathematics, Science, Social Science and the languages. You cannot redo the whole set of subjects just to lift an already-good result, and you cannot touch the internal assessment — those 20 marks per subject are fixed by your school and carried forward.
How the final marksheet is worked out
This is the detail that removes most of the fear. For every subject, CBSE takes the higher of your two theory scores — the first exam or the second exam, whichever is better. A weaker second attempt cannot drag down a stronger first attempt, so appearing again carries no downside on marks. Your internal assessment score stays the same across both. The consolidated marksheet and passing certificate, showing the best score in each subject, is issued after the second exam results, expected around the end of June 2027.
The trap: treating Exam 1 as a mock
The most common mistake this system will cause is students quietly deciding that the February exam is "just the first attempt" and the real effort can wait until May. That plan fails for simple reasons. The May window is short and lands right when Class 11 admissions, stream decisions and coaching for competitive exams are all happening. Preparing thoroughly for a subject twice in one year is exhausting. And most students who go in under-prepared in February do not suddenly find three clear weeks of focus in May. Prepare fully for the first exam. Keep the second one in reserve for the one or two subjects where a result genuinely surprised you.
Planning your year around two dates
Your year-long preparation does not really change — it still needs to peak in February. What changes is only what you do after the first result. Through the year, keep pace with school and close any gaps carried over from Class 9. From about November into December, do a first full revision pass so every chapter has been seen properly at least twice before the pre-boards. January is for previous years' papers and CBSE sample papers under timed conditions. February and March are for the exam. Then, when results come out in April, look honestly at each subject: if one or two are clearly below what your practice suggested, and lifting them would matter for Class 11 or a scholarship cut-off, use the May sitting for exactly those. Otherwise, accept the result and move on. For a month-by-month version of this plan, see our CBSE Class 10 board exam 2027 preparation timeline, pair it with a realistic daily study timetable, and use the CBSE Class 10 sample papers practice plan for the January paper-solving stretch.
Key dates at a glance
These follow CBSE's announced framework and widely reported timelines. The Board confirms exact dates only when it publishes the date sheet on cbse.gov.in, so treat the months below as expected, not fixed.
Exam 1 (compulsory): February–March 2027, all subjects, full syllabus
Exam 1 results: around April 2027
Exam 2 (optional): May–June 2027 — improvement in up to 3 subjects, plus compartment and absent cases
Exam 2 results: around June 2027
Final consolidated marksheet: after Exam 2 results, showing the best score per subject
Scoring rule: higher of the two theory scores counts; internal assessment carried forward, not repeated
What this means for parents
The safety net is real and worth being glad about, but it works best when it is never needed. The right message to a Class 10 student this year is not "there are two chances now" — it is "prepare properly for February, and we have a backup for the odd subject that doesn't go to plan." Watch for the subjects where school test marks and effort do not match, since those are the ones a second sitting is genuinely useful for. Maths and Science are the usual candidates, because one shaky concept there quietly breaks every chapter built on top of it.

Where tuition fits
A two-exam calendar rewards steady, chapter-by-chapter preparation and punishes the "I'll fix it in May" approach. That is where focused help matters through the year rather than in a panic at the end. TutorHive's CBSE online tuition and Class 10 CBSE Maths small-batch tuition follow your school syllabus in order, with doubt-clearing and previous-paper practice built into the pre-board stretch so the February exam is the one you are ready for. For subject-wise strategy, read how to score 90% in CBSE Class 10 boards, and use the chapter lists for Maths, Science and Social Science to build your revision plan.
Frequently asked questions
Is the CBSE Class 10 board exam really happening twice in 2027?
Yes. From the 2027 session, CBSE conducts the Class 10 board examination in two sittings. The first, expected in February–March 2027, is compulsory for every student. The second, tentatively in May–June 2027, is optional and meant for improvement. Class 12 is not affected and continues with one annual exam. Exact dates are confirmed only when CBSE releases the date sheet on cbse.gov.in.
Do I have to appear for both CBSE Class 10 board exams?
No. Only the first exam in February–March is mandatory. If you are satisfied with those results, you are done and that becomes your final result. The second exam in May–June is a choice you make afterwards if you want to raise your score in some subjects, if you were placed in compartment, or if you missed a paper in the first sitting.
Which subjects can I reattempt in the second board exam?
A student who has passed can appear again in up to three subjects out of Mathematics, Science, Social Science and the languages to try to improve the score. Students in compartment reappear only in the subjects they did not clear. The syllabus for the second exam is the same full syllabus as the first.
If I score lower in the second exam, will my marks go down?
No. CBSE applies a best-of-two rule for each subject, so the higher of your two theory scores in that subject is what appears on the final marksheet. A weaker second attempt cannot pull down a stronger first attempt. Internal assessment marks from your school are carried forward unchanged and are not taken again.
Does the second exam replace the old compartment exam?
Yes. The separate supplementary or compartment exam has been folded into this second board examination. The same May–June sitting now serves three groups: students improving marks in up to three subjects, students clearing a compartment in one or two subjects, and students who were absent for a paper in the first exam.
Has the Class 10 exam pattern or marking scheme changed?
The structure is the same as recent years. Each main subject is 100 marks: an 80-mark theory paper of three hours plus 20 marks of school internal assessment, with 33% overall needed to pass. Recent sample papers keep roughly half the paper as competency-based questions, about a fifth as objective or MCQ type, and the rest as short and long written answers.
