Dear Meena,

Your goals should be clear and you should work accordingly to acheive your goals.

You should be self determined and motivated to acheive your aim.

You can make your time-table and try to follow it. You can set your daily and weekly targets.

While studying you can also make your important notes. So, that your concentration didn't break.

Avoid the things which distract you. If you are tired from your studies you can take short break.

Good Luck!!
