How to Prepare for the Class 10 Nepali Exam?
The first thing you need to do is to read all the chapters perfectly. Summarize each chapter which will help you in writing the long answer related to the chapter.
For the grammar part, all you need to do is practice. Try to solve as many problems from the model question and your practice book as well.
Also, watch some old questions for a better idea of what kind of questions will be asked in the board exam. However, it is confirmed that none of the questions asked in the last 10 years will be repeated in your board exam.
