CBSE 12 Science Exam Timing 2025
The CBSE 12 science exams were conducted in a single shift, typically starting at 10:30 AM. The CBSE science exam duration varies depending on the subject. Major subjects like Physics, Mathematics, Chemistry, and Business Studies have a 3-hour duration. Vocational and specialized subjects, such as Tourism and Dance, generally have a shorter duration of 2 hours.
How to Complete the CBSE Class 12 Science Board Exam in Time?
To achieve full marks in the CBSE Class 12 science exam, a well-structured study plan, and effective preparation strategies are crucial. While science is primarily a theoretical subject, it requires a deep understanding of concepts, strong analytical skills, and a systematic approach.
The CBSE science question paper includes a diverse range of question types, including understanding-based, application-based, remembering-based, high-order thinking skills (HOTS) questions, and evaluation-based questions. To excel in the exam, students must develop a comprehensive understanding of the concepts, practice regularly, and employ effective study techniques
Before attempting the actual CBSE 12th science exam, practice with sample papers. Set a timer for the same duration as the 12th CBSE science exam (e.g., 2 hours 50 minutes for a 3-hour CBSE exam). Within this time, simulate the entire exam process: reading the question paper, solving questions, and reviewing the answers.
Effective time management is crucial for the CBSE 12th science exam success. Practice with sample papers to develop this skill. If they have not practised beforehand, prioritise the second-last section first, followed by the last section, and then the first and second sections. This strategy ensures the candidate allocates sufficient time to the lengthier, more complex sections. For instance, in a four-section exam (A, B, C, D), allocate 50 minutes for Section C, 60 minutes for Section D, 30 minutes for Section B, and 20 minutes for Section A.

Hello
Yes, if you’re not satisfied with your marks even after the improvement exam, many education boards allow you to reappear as a private candidate next year to improve your scores. This means you can register independently, study at your own pace, and take the exams without attending regular classes. It’s a good option to improve your results and open up more opportunities for higher studies or careers. Just make sure to check the specific rules and deadlines of your education board so you don’t miss the registration window. Keep your focus, and you will do better next time.
Hello Aspirant,
Yes, in the case that you appeared for the 2025 improvement exam and your roll number is different from what was on the previous year’s marksheet, the board will usually release a new migration certificate. This is because the migration certificate will reflect the most recent exam details, roll number and passing year. You can apply to get it from your board using the process prescribed by them either online or through your school/college.
