Answer 2

We cannot determine whether they'll be easy or not. As we know term 1 examination will be objective.

So. you can consider these tips for your preparation-

• Focus on building your concepts through NCERT. As we know, the objective section will include case and assertion-reason based questions that are based on practical, real-life situations. For that you need to know your theory well, only then you can work on its application. So read all the chapters from NCERT well and highlight the finest details of the chapter.

• Next, you have to practice a lot of objective questions, which can only be possible by using a well-formed question bank i.e Educart question bank. It provides more than 50% of MCQs (Assertion-reason + Competency (case-based MCQ) style) in each chapter based on the new pattern and reduced syllabus of cbse board exam. The topic notes given with each chapter contains important points of a chapter with new pattern case-based MCQs as examples to explain the theory. The solutions come with an explanation and related theory which helps in understanding the concept better.

Keep on revising the notes to retain the information for the long term.

Hope it helps!
