Hello Seema,

First of all, you should read NCERT books of Physics, Chemistry & Biology of class 11th & 12th at least 5 times. You should also try to solve the previous years question papers again and again, and start giving mock test. In this way you will prepare yourself for the board examination as well as for the NEET exam.

The main thing is that you have to build your concentration level, then only you can stay focused on your goal. I would like to say that please limit the study time between 10 to 12 hours and please increase your concentration and speed of reading, understanding and solving the problems then you will not face any kind of difficulty.

For preparation of exam, the most important thing is your confidence after that you should know the whole syllabus and make your plan properly for learning new chapters, solving the numericals and revision. All three things should be the part of your preparation strategy in daily routine.

In this way you can make it possible.

All the best
