Sir i am now feeling that i am not fit for JEE.Today I want to tell you that i am not at all serious about JEE in my 11th.But after coming in 12th I became a lot more serious.But truly i say that I have given only 40% of my real ability to studies & now after coming with many aspirants of Jee on this site I feel that i am still not prepared even for AIEEE.I am thinking of dropping bcoz I am feeling that I will also spoil my 12th boards also.In the dropping year I will try to give my 100% on the studies & to crack JEE.
