JEE exam is not very difficult. One has to get their basics right and little hard practise of problems is all you need to excel in JEE exam. The topics in which you are realtively stronger, you do not need to work more on those topics. Concentrate on the topics which you are not comfortable with.
all the best !!
Just be cool. Exam will not be very tuff, but require a 'tedhi soach'. Just do as much practice as u can, & don't loose confidence till last!!!!! Prepare urself mentally, than u will beat JEE.
