Exam Pattern

1. The following is distribution of topics, indicative weightage, and the amount of choice within each section

  • Section 1: Unit 1 and Unit 2: (weightage 20 marks), Two questions of 10 marks each with one question from Unit 1 and the other from Unit 2. Internal choice in these units should be given as 2 out of 3 questions
  • Section 2: Unit 3: (weightage 20 marks), Two questions out of Three for 10 marks each.
  • Section 3: Unit 4: weightage 20 marks), Two questions out of Three for 10 marks each.
  • Section 4: Unit 5: (weightage 15 marks), Three questions out of Four for 5 marks each.

2. There would be no compulsory question in any of the sections.

3. The internal assessment would comprise of 10 marks Class test, 10 marks Class test/assignment. Attendance will carry 05 marks.

4. the question paper will include internal choice in each section with limited number of sub-parts.

5. In order to achieve uniformity in evaluation of final answer scripts, it was decided to include the following note in final question paper:

  • All questions within each section are to be answered in a contiguous manner on the answer sheet. Start each question on a new page, and all sub-parts of a question should follow one after the other.
  • All intermediate calculations should be rounded off to 3 decimal places. The values provided in statistical tables should not be rounded off. All final calculations should be rounded off to two decimal places.
