well my dear first and for most thing is to believe in yourself and don't take tensions
work hard very hard
keep your eye on only your goal
ask doubts from coaching centres whenever you are in prob...........
just do all the assignments at time and keep revising them
these 2 years can change your life
you have taken good books already
take resnic haliday walker also
for phy
and for chem take arihant for org and for inorg
be positive you can do it
best of luck for jee 2009
