Answer 1

See, there are no tricks for becoming a good student. Its a habit that develops or you need to develop over time
For being a good student:

Study well. Complete your work before time.Study some part of what is going to be taught the next day before hand.Even of you feel some subjects are boring, still study them and get better on subjects in which you thoroughly enjoy (try to amass as much knowledge in those subject as you can).utilize your time to best possible way you can (eg. if you feel a particular subject is boring or you have known about that topic, you can either study something else at that time or go out and play orgive way to your hobbies).Take part in a lot of co-curricular activities.
Have a good temperament but be notorious as well. 
we have to practice until we can claim our goal or aim
