CBSE Class 12th  Exam Date : 01 Jan' 2025 - 14 Feb' 2025

CBSE Class 10 board exams are very important in a student’s academic journey. CBSE is conducting the class 10 board exams from 15 February 2025. As we know the CBSE exams are less than one month away, hence it is very important to prepare strategically for the exams. As exam time approaches you need to design your study sessions and prioritize your study material. It is not possible to study all the topics in this short duration, so focusing on the important topics with high-weightage marks can boost the student’s marks and help them to succeed in the Class 10 board exams.

Questions related to CBSE Class 12th

Have a question related to CBSE Class 12th ?

Changing from the CBSE board to the Odisha CHSE in Class 12 is generally difficult and often not ideal due to differences in syllabi and examination structures. Most boards, including Odisha CHSE , do not recommend switching in the final year of schooling. It is crucial to consult both CBSE and Odisha CHSE authorities for specific policies, but making such a change earlier is advisable to prevent academic complications.
