CBSE Class 10 students now sit two board exams in the same academic year, and for families in the UAE the new system raises practical questions. What is Phase 1? Who can take Phase 2? And is it worth attempting the second exam at all?
This guide explains the CBSE Class 10 two board exams 2027 in plain language. It covers how both phases work, who is eligible, how scores are counted, and how to decide which exam to attempt. CBSE released the 2027 date sheet on 6 November 2026. The Phase 1 theory exams run from 16 February to 9 March 2027, and Phase 2 is planned for May 2027, with dates still to be announced. For subject-wise papers, see our CBSE Class 10 and 12 date sheet 2027 guide.
This post focuses on strategy for UAE students rather than the timetable, so you can plan your preparation with confidence.
Since 2026, CBSE Class 10 has had a main exam and a second exam. The table below shows how the two phases compare.
| Feature | Phase 1 (Main Exam) | Phase 2 (Second Exam) |
|---|---|---|
| Status | Compulsory for every Class 10 student | Optional, for eligible students only |
| Timing in 2027 | 16 February to 9 March 2027 | May 2027 (dates awaited) |
| Subjects | All subjects | Up to three subjects from Science, Maths, Social Science and languages |
| Practicals and internal assessment | Held once in school, from 1 January 2027 for most schools | Not repeated and cannot be improved |
| Who can sit | All regular students | Students who sat Phase 1 and qualify for improvement or compartment |
| Score counting | Your baseline result | The higher score in each re-attempted subject counts |
These details come from CBSE announcements and circulars. Always confirm the latest information with your school and on the official CBSE website.
Phase 1 is compulsory for every student
CBSE’s notification states that every student must appear in the first board examination. Schools register all Class 10 students for it, and it covers every subject. For 2027, the Phase 1 theory exams run from 16 February to 9 March 2027.
Practicals and internal assessment are held once
Practicals, projects and internal assessment take place in school, and for most CBSE schools they are scheduled from 1 January to 13 February 2027. They are not repeated for Phase 2, so the marks you earn in school carry forward.
Your Phase 1 result becomes your baseline
If you are happy with your Phase 1 result, you do not need to sit Phase 2. If you re-attempt any subject, the better score in that subject is used for your final marksheet.
Phase 2 is optional and only for eligible students
The second exam is not compulsory. CBSE has said it is meant for students who passed and want to improve their marks, students placed in compartment, and students who need both.
You can re-attempt up to three subjects
Improvement is allowed in up to three subjects chosen from Science, Mathematics, Social Science and languages. You can only re-attempt subjects you already sat in Phase 1.
The better score counts
For each subject you re-attempt, the higher of your two scores is used for your final result. A weaker Phase 2 performance does not pull your marks down.
Internal assessment cannot be improved
Practical and internal assessment marks stay as they were in Phase 1. Phase 2 only gives you another chance in the theory papers.
Students absent in three or more subjects cannot sit Phase 2
CBSE has clarified that a student who misses three or more subjects in Phase 1, or fails three or more, is placed in the Essential Repeat category. These students take the main exam again the following February instead of sitting the second exam.
Your school submits the entry
Registration for Phase 2 is done by your school through the List of Candidates (LOC) process after the Phase 1 results. Students cannot register on their own, so tell your school early if you plan to sit it.

Every student sits Phase 1, so the real decision is whether to attempt Phase 2 and in which subjects.
Treat Phase 1 as your real exam
Prepare for Phase 1 as if it is your only attempt. Phase 2 works best as a safety net, not as a plan.
Consider Phase 2 if
Skip Phase 2 if
Pick subjects with the biggest realistic gain
Because you can improve only three subjects, choose the ones where the gap between your score and your potential is largest. Review your Phase 1 performance by chapter and question type to see which gaps can be closed quickly.
Ask these three questions before you decide
Phase 2 can overlap with the start of Class 11
CBSE schools in the UAE follow an April to March academic year, so Class 11 usually begins in April, before the May second exam. UAE school leaders have pointed out that students who sit Phase 2 need to balance new classes with revision, so plan your time early.
Exam centres matter
In 2026, UAE school coordinators explained that students sit the second exam at the same centres as the first, so students who have moved away may need to return. Check your school’s arrangements for 2027.
Class 11 admission planning
Students who do not qualify in Phase 1 may be given provisional Class 11 admission, confirmed after the second exam result. Check your own school’s admission policy so there are no surprises.
If you want structured support, our CBSE tutors in Dubai can help you plan both phases around your strengths and gaps. Here is a simple framework you can follow.
Now to December: finish the syllabus and build the basics
Complete every chapter, fix weak concepts early and keep up with projects and practical work assigned by your school.
January to February: timed practice and practicals
Practicals begin in January for most schools. Alongside them, practise full papers under timed conditions and review every mistake.
Phase 1 weeks: revise, rest and review each paper
Keep revision light between papers, protect your sleep, and note what went well and what did not after each exam.
After Phase 1: analyse and decide
Once your results arrive, compare them with your Class 11 goals. Decide on Phase 2 quickly, because your school submits the entries soon after the results.
Before Phase 2: fix specific gaps
If you sit the second exam, focus only on the one to three subjects you chose. Work through past papers, correct recurring errors and keep up with Class 11 homework.
The CBSE Class 10 two board exams 2027 give students a safety net, but the best results come from preparing well for Phase 1 and using Phase 2 only where it makes a real difference. Check your eligibility, choose subjects with the biggest realistic gain, and plan around the start of Class 11 if you live in the UAE.
