A fever on the morning of the paper, an accident, a death in the family: every year some students miss a board exam for reasons they could not control. Missing a paper does not end your year, but the rules are strict, so the next few days matter. This guide covers CBSE, using the Board's own 2026 circulars. State boards, ICSE, JEE Main and NEET-UG have their own rules, so check their current notices.
What happens if you miss a CBSE Class 10 board exam?
From 2026, Class 10 has two board exams a year, and CBSE says the first one is compulsory. Its notification of 14 February 2026 states: "It is mandatory for all the students to appear in the first Board examination."
The same notification sets the key limit. A student who does not appear in 3 or more subjects of the first exam cannot sit the second exam; they are placed in the "Essential Repeat" category and can take the exam only in the main February exams the next year. CBSE adds that this applies "because of any reason" and it will not answer requests for exceptions.
Missing one or two papers does not trigger that bar. How those papers show on your result follows CBSE's rules, and if your result says Compartment, CBSE's April 2026 circular on the second exam lets you sit the second exam in that category. That circular set the fee at Rs 320 per subject for schools in India, and it says the school submits the names of first-chance Compartment students. For how the two exams fit together, read our guide to CBSE's two board exams in Class 10.
What happens if you miss a CBSE Class 12 board exam?
Class 12 has one main exam and a supplementary exam. CBSE's circular of 30 June 2026 lets a regular student whose result is Compartment take the supplementary exam in one subject. A student with 6 subjects and Compartment in two may choose either one. In 2026 the school had to submit names between 30 June and 8 July, the fee was Rs 320 per subject in India, and the exam was held on 28 July.
If you are ill or unreachable, note this: schools must submit the names of all Compartment students "even if they are unable to contact the students", and a student whose name is not submitted loses the chance to sit the supplementary exam. The circular also says a student placed in Compartment gets a maximum of three chances to pass. Our explainer on CBSE supplementary exam rules covers the categories in more detail.
The one narrow exception: students the Board exempted for national or international sports events took a special Class 12 exam on 11 and 13 April 2026. It does not cover illness or other emergencies.
Who should you contact, and what documents do you need?
Your school is the link to CBSE; the Class 12 circular tells Compartment students to ask their school to put their names forward. Work in this order:
On the day, a parent calls the class teacher or principal. Do not wait for the result.
Keep proof of the emergency: a doctor's certificate, hospital discharge summary or police report. CBSE's circulars do not list fixed documents, so ask the school what it wants.
Keep your admit card and roll number to hand.
Once results are out, confirm in writing that the school has put your name on the list for the next exam.
If the school cannot help, contact your CBSE regional office.
How do you prepare for the re-exam?
A worked example: Riya, in Class 12, misses Chemistry with dengue and her result says Compartment. Suppose she has about seven weeks before the 28 July exam. A simple plan:
Weeks 1-2: rest as the doctor advises, then light revision of the chapters she found hardest.
Weeks 3-5: one past paper section a day, marked against the marking scheme.
Weeks 6-7: two full timed papers a week, and fixing every mistake the same day.

When should you get help for the stress?
Missing a board paper upsets the whole family. If low mood or panic does not lift, or gets in the way of sleep and food, talk to a doctor or counsellor. Tele MANAS, the government's mental health helpline, is a toll-free, 24/7 number: 14416. Our guide on when exam stress needs professional help explains the signs to watch for.
Your next step: call the school today and write down what they tell you.
