From the above table, it is understood that Units 3, 7, and 12 have the highest weightage and hence must get more time to study. The rest of the units also need attention as per the marks allotted. Typically, Chemistry papers are not challenging but tricky, as reported by students in previous years. So an intelligent approach to studying Chemistry must be developed, keeping the syllabus in mind. Also, the subject demands a fair amount of memorization, but the clarity of concepts needs to be there. The Theory paper is for 70 Marks and the total time allotted to solve it is 3 Hrs. The question paper gets divided into four sections.

1. Section A: Q. No.1 contains Ten multiple-choice types of questions carrying One mark each.

                  Q. No. 2 contains Eight very short answer types of questions carrying One mark each.

2. Section B: Q. No.3 to Q. No. 14 are Twelve short answer types of questions carrying Two marks each. (Attempt any Eight).

3. Section C: Q. No. 15 to Q. No.26 contain Twelve short answer types of questions carrying Three marks each. (Attempt any Eight)

4. Section D: Q. No. 27 to Q. No. 31 are Five long answer types of questions carrying Four marks each. (Attempt any Three)
