## Questions for Section ‘C’

Preparation for Section C

Make a checklist for these questions, so you may have an idea that how much you have prepared till now.
For Section ‘B’ and MCQs

Go through Past Papers, At least, at least last 10 years exam papers.

## Material for Preparation for Exams

Go through this material … Solve everything… If there is something difficult or confusing, clear it before mid-term examinations.

CHAPTER 1 – MCQs w/ Solution

CHAPTER 2,3,4 – MCQs w/ Solution

CHAPTER 2,3,4 – THEORETICAL QUESTIONS & NUMERICAL PROBLEMS
For dimensional part of Chapter 1 – Go through five year papers – I’ll also discuss that in the class

Other than that there will be revision of Chapter 2 + difficult concepts of 3 & 4 and a discussion about “The Exam Paper Pattern of BIEK-XI Physics & How to solve that Question Paper”
