Tell me

Another a few days to call April a month. Final examination is coming. I have not more than 20 days to do the preparation. Thinking of it give me a cold shiver. How am I not afraid? I have 3 assignment to due soon, around 6 chapters for each subject, for 5 subject, so much and so much of unsolved calculation and more than ever does-not-make-sense notes to memorize. Seriously, the coming month is going to be a real hectic one. Tell me how to gain more concentration(not the electron or hole concentration), I mean the real peaceful and undisturbed mind. Tell me where to buy determination. Again, tell me where can I get confidence. Arrghhh.....Help me, to eliminate the laziness, and unconsciousness. And also to strain away STRESS from my mind...please
