By examining the syllabus and paper pattern, students can prioritize their study plan based on the marks distribution.
- Follow Right Books: Students should start with completing the NCERT books first and they can refer to other books. The Physics, Chemistry, Biology carry almost equal weightage so don't neglect any subject. After this, solving CBSE 10th sample papers or previous papers is the best way to prepare.
- Make A Study Schedule: A Study schedule is one of the best ways to make your study organized. Listing down the important chapters and topics can increase the productivity of the student. Covering the important topics should be the priority, and cover the least important chapter in the end.
