Hello Pankaj,

See first of all you need to sit and relax. Then ask these questions from yourself like what you need to do in your life and what will be your Aim and where do you see yourself after few years if you choose your Aim. After answering these questions you get to know what your mind is thinking and what you needs to do.

Clearing any exam is not that difficult but to decide and whole heartedly indulging in that is the most important key. Do remember that failure is also the important part of the exam as well as for the life . Don't be scared of failure instead motivate you to work even more hard.

In the meanwhile as your prepare for your exams do remember not to compare your life with others , as they are enjoying and your studying like anything. Once you clear your exam and be in the place you wanted to achieve you'll remember this time of preparing and the hard work you had put in for achieving it.

Hope this will help you for focusing and in decision making.
