How to practice questions in the right way for NEET?

It depends on the subject and whether you are studying the chapter or revising the chapter.
If you are studying the chapter then give yourself plenty of time for solving the questions as you will be testing your knowledge and understanding of the chapter, whether you have understood the concepts or not.
When you are done studying the chapter, during revision you need to solve the questions under a time limit.
Like for physics you need to set a timer for 40mins for 20 questions i.e the time will be double to the number of questions. For bio the time will be half the number of questions i.e 15 minutes for 30 questions and for chemistry the time will be in between these two subjects.
This exact same concept will be applied in your neet paper where you need to complete the entire bio paper in max 40 mins.
So be consistent with this method and you will see progress.
