how many questions we should practice from a math chapter in class 10th?
Dear aspirant,
For class 10 board exams, the number of questions that you need to practice depend on the difficulty level of the topic and how much practice you need to get comfortable with the topic. Focus on finishing the exercises from the textbooks first and then finish off the previous year questions. This is a must. If you find difficulty in some subtopic, practice as many questions as it takes for you to get comfortable with it.
Hope this helps.
