Dear Mainak,

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

Try to give quality time to your study stay away from all the distractions.

If you want you can make your proper time table so that you can easily cover your syllabus and you get proper time for revision. You can set your daily targets.

You need to be clam and focussed. Always remember this is the time when you can make your career. Now, it's upto you in which direction you want to make it. 

Good Luck!!
