CBSE released the 2027 Class 10 date sheet on 6 November 2026, and the main exams start on 16 February 2027 (CBSE date sheet, 2027). If you start on Sunday 3 January, you have exactly 45 days before Mathematics on 17 February. Here is how to split them across five subjects, with rest built in and a fix for pre-boards.
Which Class 10 board paper comes first in 2027?
According to the official CBSE date sheet for 2027, the five main papers fall on these dates:
Mathematics (Standard and Basic): Wednesday 17 February
Science: Monday 22 February
English (both courses): Friday 26 February
Hindi Course-A and Course-B: Wednesday 3 March
Social Science: Monday 8 March
All papers begin at 10:30 a.m. Painting, an elective, opens the exams on 16 February; of the main subjects, Maths comes first, so it has to be ready by Day 45. After it, there are four clear days before Science, three before English, and four each before Hindi and Social Science. Use those gaps for one last timed paper and your mistake log, not new chapters.
What does a 45-day plan for Class 10 boards look like?
The plan leans on two well-tested habits. In a 2006 study, students who took recall tests remembered more of a passage a week later than students who reread it (Roediger and Karpicke, Psychological Science). A review of 317 experiments on spacing found that the best gap between study sessions grows with how long you need to remember (Cepeda and colleagues, Psychological Bulletin). So the plan tests you early and comes back to every subject every few days.
Days 1-7 (3-9 January): audit. Sit one timed sample paper each in Maths and Science, and one section each of English, Hindi and Social Science. Mark every chapter green (solid), amber (shaky) or red (lost marks). Day 7 is a half-day off.
Days 8-21 (10-23 January): repair. Two subjects a day: a heavy one (Maths or Science) in the morning, a lighter one (English, Hindi or Social Science) later. Red chapters first. Close the book and write what you remember before checking. Days 14 and 21 are half-days off.
Days 22-35 (24 January-6 February): papers. One full timed paper a day, rotating subjects, marked the same evening. Every lost mark goes into a mistake log. Days 28 and 35 are half-days off.
Days 36-45 (7-16 February): taper. Maths every day, Science on alternate days. Two more timed Maths papers, then redo only the questions in your log. Day 42 is a half-day off. Days 44 and 45 are light: formula sheet, early night.
If a red Science chapter fails because the idea itself is unclear, a lesson in the Fermi Concept Library can rebuild it before you test yourself again. If your Maths log shows the same wrong method again and again, the Fermi Problem Library has worked problems with a step-by-step solver that explains the reasoning rather than printing an answer.
Where do you get CBSE sample papers, and how should you mark them?
CBSE publishes Class 10 sample question papers with marking schemes for 2026-27 for every main subject. Mark against the official scheme, step by step, so you see where marks for working and units go. For more practice, read our guide to using previous-year papers without memorising answers; the six-week Class 10 science revision plan goes deeper on one subject.
What if your school's pre-boards fall inside the 45 days?
Board dates are fixed by the CBSE date sheet; pre-board dates come from your school. Use this template:
Write each pre-board paper into the plan. It replaces that day's slot and counts as a timed paper.
The day before each pre-board, revise only that subject.
Within two days of each paper, sort lost marks into three bins: did not know, knew but slipped, ran out of time. Add them to your log.
Keep the half-days off. If something must go, drop a light-subject repair slot, never sleep.
When pre-boards end, rejoin the plan at the phase the calendar shows.
Worked example: pre-boards run 18-28 January, Days 16 to 26. Repair Days 16-21 become revision for each next pre-board paper, and the papers themselves stand in for timed practice. Spend Day 27 on the red chapters they exposed, keep Day 28 as a half-day off, and run the papers phase from Day 29 to 35.
How much sleep do you need in the last 45 days?
Teenagers aged 13 to 18 should sleep 8 to 10 hours in every 24, says the American Academy of Sleep Medicine consensus statement. Plan study hours around that, not the other way round.
If worry starts to crowd out sleep or meals, talk to a parent, teacher or school counsellor, or call Tele MANAS, the government's free mental-health helpline, on 14416 (Ministry of Health and Family Welfare). Starting later than 3 January? Our plan for board prep that had not started by December shows how to cut it down.
