CBSE EXAM LATEST UPDATE
The Class 11 exams depend on the schools, as they decide when to conduct the exams. Usually, the Class 11 exams are held a few months before the final board exams. This gives you the opportunity to prepare for the final board exams and also mentally prepare for them. Therefore, it is better to contact your school regarding the Class 11 exams, and also take advantage of the complete information provided here for the final board exam.
Central Board of Secondary Education (CBSE) has announced class 12 Board exams date. This year class 12th board exam will be started from 15 February 2025 and will last upto 04 April 2025, it will take around 49 days to complete the class 12th board exam. The first exam will be held on 15 February 2025 for Entrepreneurship (Including Vocational Students) subject and the last exam will be held on 04 April 2025 for Psychology subject. The practical exams/Internal Assesment/Projects & the board's annual theory examinations are scheduled to start w.e.f 01th January 2025 and 15th February 2025.
