Can any one tell me how frequently should i revise cause we tend to forget stuff easily after a few days which scares me a lot ?
Try making shortnotes..
Jst love the subject then you can get interest on subject for example if you want to read a lesson in physics in optics then you have to see how the light used in our regular way in this way you can have an interest and complete subject in time
Just revise once on Sunday while watching tv or songs
Just go through your notes once ,it would require no extra time the above activities can be exchanged with while in phone or chatting or anything
It really works.
This is mainly dependence on interest, although we can't forget our routine action .confine ur subject to be ur part of time ,never work for the sake of marks .work for the sake of knowledge which ill gradually optimize ur grades.the all u need to do is focus by gaining cosmic energy through meditation .
