Hi student,

The main reason for not being able to concentrate on studies is the number of distractions in your way. You need to improve your self control by not being distracted by things like an unimportant text message, watching television, etc. You need to decide before starting studying about how much you are going to finish or how many hours you will study. You can also try meditation to improve concentration. You should have a goal, so that you remember that you have an aim to achieve before you get distracted.

Hope it helps.

Good luck.
