Above all topics are very very important in NEB examintion of physics for 2021.In this pandemic situation and last year of old course, most of take from important topics.

In 2020 NEB examination of physics Questions asked 40 marks at that pandemic .we think it also happen in this year.

Above given topics are also important in our other examination like IOE, IOM, BSC CSIT. so, who want prepare such high level examination, they can study such field deply.

Lastly , we say all of you, best prepare for you incoming NEB examination.Good bye for now.

### 1)Can all of above questions are important for NEB examination?

Yes,all of above questions are important for NEB examination.

### 2)What you prefer to read above question?

Ues, it is very imp questions for your exsmination.

Best of luck for all of you
