Over the year you would have worked a lot for this exam and wonder what to do these days. Don't try to learn anything new. Go through the concepts fully. Learn all formulas and derivation (Derivation helps to recover formula during exam). Don't continuously stick with books. Go out. Get fresh Air. Play your favorite sports. Don't waste time in TV, FB, IPL What's App etc. Listen to good music. Take good food. Change your biological clock back to normal. i.e. go to bed on time. Enjoy your days. Enjoy your exam
