PHYSICS

(study plan and analysis)

Lesson -1 ‘’Electrostatics’’ is a big lesson. Needs a lot of input and understanding. But it is one of the most IMPORTANT lessons. So we have to pay great attention to it.

Things to know:

• There is no need to study inside questions. All the questions are covered in the book back [So, pay attention to it]
• Then, the numerical problems need a lot of attention cause, there are 24 examples and 15 problems in the book back exercises. It may be asked as compulsory problems and even in the 5 marks.
• Then as usual one marks. 15 marks are asked in the exams. Compulsory 1 will be asked from the first lesson. 

Study Plan:

This study plan is for 9 days. Yes, it is not sufficient for all. But in this session 2020-21, we don’t have enough time to spend on this one lesson. And even if the first lesson is one of the most important lessons and contains many important questions and topics, In public exams out of 70 approximately for only 8 marks, the questions are asked from this lesson. Take a look at this.
