CBSE Class 12 Biology Important MCQs 2024: Today’s teaching has become different from traditional teaching approaches in many aspects. Earlier, teachers used to follow autocratic teaching strategies that were content- and teacher-centred. The teacher’s role used to be primary, and the students’ involvement was after that.
Now the scenario is quite different, as the democratic teaching strategy is now replacing the traditional teaching strategy. The democratic teaching strategy is student-centred. Discussion, discovery, project, assignment, brainstorming, etc. are a few categories of such types of teaching strategies.
The MCQ (multiple choice question) method is one of the most effective ways of checking the progress of students. Here, students get more than one option from which they need to pick the right answer. This uses their recalling ability. MCQs are important from an exam point of view. The CBSE Class 12 Board exams will have more than ten MCQs in each paper. To help you prepare for the CBSE Class 12 Biology board exam in 2024, we have highlighted some MCQs from Chapter 13 Biodiversity and Conservation. These MCQs follow the revised syllabus and are picked from the revised NCERT Class 12 Biology textbook. Check it out and download the free PDF.
