CBSE Class 12th Exam Date:17 Feb' 26 - 17 Feb' 26
The Central Board of Secondary Education (CBSE) conducts the practical examination for Class 12 students, and the CBSE Class 12 Biology lab manual 2026 is a useful resource to prepare for the examination. Throughout the academic year, the students need to perform several practicals in their school laboratory under the guidance of their teacher. In the practical examination, the students need to perform a few of the practicals and appear in the viva. The lab manual for the CBSE Class 12 is published by the NCERT, and this is available online on the official website. The CBSE 12th Biology lab manual 2026 includes exercises based on the chapters included in the Biology book, along with investigatory projects.
Thousands of students in the Physics, Chemistry, Biology (PCB) stream had planned to add subjects like Mathematics to pursue engineering, economics, computer science, or BTech via JEE. With the additional subject exam cancelled, their options are now limited, forcing many to stick to medical pathways or expensive private colleges.

Hello Pruthvi,
Taking a drop year to reappear for the Karnataka Common Entrance Test (KCET) is a well-defined process. As a repeater, you are fully eligible to take the exam again to improve your score and secure a better rank for admissions.
The main procedure involves submitting a new application for the KCET through the official Karnataka Examinations Authority (KEA) website when registrations open for the next academic session. You must pay the required application fee and complete all formalities just like any other candidate. A significant advantage for you is that you do not need to retake your 12th board exams. Your previously secured board marks in the qualifying subjects will be used again. Your new KCET rank will be calculated by combining these existing board marks with your new score from the KCET exam. Therefore, your entire focus during this year should be on preparing thoroughly for the KCET to achieve a higher score.

Yes, you can switch from Science in Karnataka State Board to Commerce in CBSE for 12th. You will need a Transfer Certificate from your current school and meet the CBSE school’s admission requirements. Since you haven’t studied Commerce subjects like Accountancy, Economics, and Business Studies, you may need to catch up before or during 12th. Not all CBSE schools accept direct admission to 12th from another board, so some may ask you to join Class 11 first. Make sure to check the school’s rules and plan your subject preparation.
