sir,

    only a few days are left for iitjee 2008.what should be my plan of study now. i have prepared all the things well and results of fiitjee aits have also been good.but as 2007 was very easy compared to that of 2006,i'm a littile bit anxious about the standard of the question.should i go through only problems now(tough or conceptual?) or go through the theory sections minutely from verma ,resnick,morrison,lee,arihant chemistry etc?will it be better to do both? what should be my plan of study for mathematics ?should i practice a lot of problems or just give exams at home ?if i practice now by giving exams at home ,will it be rather waste oif time or going through the theories will help me in solving tough and conceptual problems more efficiently in the exam hall?what should i do everyday to reduce tension and increase my concentration.as the exam is from nine o'clock in the morning,about  how many hours of sleep is needed? feeling a little bit tensed as the exam is approaching.
