i am actually planning to opt for long term. can someone pls let me know the usual success rate (i qualified in mains but did not get a nice seat]. could u pls let me know about someone who attempted the second time and made it up in a very good iit

@ sreshta 
Yes , i have a very good examples that the peoples are taking drop for a year and prepare for it , and made it to iit kanpur and roorkee . 
i hv 1 example of a student that he got 25 in the jee main frst attempt and not qualified , and in the 2^nd attempt he scored 210 and qualified mains and advanced also . 
but in this long term u need to work very hard , nearly double the amount of hours . 
LEARN from your mistake and try to strong that as far as possible . 

as u have a very good grasp on both classes take test series as much as possible . 

and remember not to repeat the mistake again . 
SO, GO AHEAD AND TAKE A DROP IF U ARE CONFIDENT  ON IT . 

ALL THE BEST ..
