A Class 12 student should prioritise board examination preparation while setting aside dedicated daily time to cover essential Class 11 topics. Focus on concepts that are frequently tested in NEET and build on current Class 12 topics, rather than trying to complete the entire backlog at once. Use weekends for revision and MCQ practice, and gradually increase NEET preparation after boards. A realistic timetable and consistent progress are more effective than rushing through the syllabus.
