Two Board Exams for Class 10: What Changed
The idea of two board exams for Class 10 wasn't new for 2027 — it actually started in 2026. The first year, students took a major examination in February and a second examination in May, if they wished to improve their results in up to three subjects.
In 2027 this system still exists, but is now streamlined. The main exams for Class 10 are scheduled to take place from mid-February to mid-March 2027, and those who wish to have a second chance will do so in May. The best of the two scores will be used on the final mark sheet – it doesn't matter if you try again!
However, this rule is only for Class 10 for now as Class 12 students will still have one exam a year.
Passing Criteria: 2026 vs 2027
This is one of the major changes in the cbse board exam 2027. Students and parents must know this one of the major changes in the cbse board exam 2027.
|
Session
|
Passing Rule
|
|
2026
|
Students needed 33% of combined marks (theory + internal assessment)
|
|
2027
|
Students must score at least 33% in theory AND 33% in internal assessment separately
|
If a subject is divided into 80 marks for theory and 20 marks for internal assessment, a student is required to obtain approximately 26.5 marks in theory and 6.6 marks in internal assessment, separately. In the past, a strong internal assessment was able to compensate for a poor theory paper. That is no longer the case and consistent preparation during the year is more important than ever.

CBSE Syllabus 2027: New Additions
The cbse syllabus 2027 expands upon the changes introduced in the 2026-27 syllabus. Some of the minor additions are:
-
A series of modules have been introduced for AI and Computational Thinking (CT) in younger classes, and from the 2027-28 academic year, these will be extended to Classes 9-12.
-
Advanced Maths and Science papers: These are optional papers (25 marks at advanced level) suitable for students who wish to extend beyond the standard syllabus and beneficial to those who wish to take competitive examinations in the future.
-
Three-language policy: The new language textbooks are rolled out, and the new structure will impact the way languages are taught and will be tested in the future.
-
Vocational and skill subjects: These continue to be introduced in addition to academic subjects, and are more practical and career-focused.
It is hoped that this will help to reduce the emphasis on rote learning and assess the level of student application of knowledge.
Class 12 Board Exam: What Stayed the Same
Not all things have changed! Here are some things you should know about that will stay the same for Class 12 in 2027:
- No second chance for annual board exam (as in Class 10)
- Grading scale is the same as 9 point scale (A1 to E2) for assessment
- On-screen marking (2026) remains to process results quickly and accurately.
- Theory + internal assessment marks remain the same for each subject.
If you are in Class 12, your exam pattern is very similar to 2026, apart from the minor changes in the exam hall rules and paper format.
Exam Security & Evaluation Updates
In 2027, CBSE has also made some changes in the conduct and monitoring of exams:
- QR codes on all answer sheets to track and authenticity
- Rough work should be carried out in the right-hand margin and clearly crossed out.
- A writing and marking policy is not to be used on the question paper.
- Strict anti-cheating measures: two years exam ban for students found using unfair means.
- Live streaming and CCTV monitoring at multiple exam centres
The following steps are designed to increase transparency of the evaluation process for all concerned, students, parents, and schools.
How to Prepare With the Right Practice Material
Practicing is more important than ever as passing criteria is becoming more and more challenging and question papers are becoming more application oriented. This is where a set of good CBSE sample paper class 10 or CBSE sample paper class 12 2026 is helpful because you can practice papers which are based on the new CBSE pattern for the new types of questions.
In addition to sample papers, you can practice chapter-wise using a well-organised cbse question bank class 10 or cbse question bank class 12. Students and teachers alike rely on resources such as Oswaal Books for such pattern-based practice papers that contain the previous year's question papers as well as the latest updates and changes in the CBSE Syllabus. One of the easiest ways to be prepared for theory as well as internal assessment is to do regular practice of sample papers and question bank along with the NCERT textbook.
Summary
The cbse board exam changes 2027 build on the reforms initiated in 2026, and not completely replace it. The two exam system for class 10, the 9 point grading system and on screen marking remain unchanged from last year. What's genuinely new in 2027 is the stricter, separate passing criteria for theory and internal assessment, tighter exam security with QR codes, and further expansion of the competency-based cbse syllabus 2027 with AI and advanced subject options. For students, the message is simple: consistent preparation throughout the year, supported by good sample papers and question banks, matters more than ever before.
