While MCQs are a crucial part of CBSE exams and practicing them can significantly boost your score, they should not be your sole focus. A well-rounded preparation strategy includes studying theoretical concepts, practicing subjective questions, and solving past papers along with MCQs. MCQs help with quick revision and testing your knowledge, but understanding the underlying concepts is key to answering both objective and descriptive questions effectively. Combine MCQ practice with a solid grasp of the syllabus for the best results in your CBSE exams.
