Can I Crack IIT JEE To Get A Seat In IIT Ghy(Electronics Or Computer Science) In One year.I Belong To ST Category

dear rahul 
its better in case any catagory attached on your name , so, just study the 12^th carefully and keep the summer vacation and 1-2 days in week for 11^th part revision . 
and keep on revisiing the past year paper as well as mock test from askiitians . 
you can easily cross jee advanced . 
just you need to understand the thing conceptwise. 
HOPE IT CLEARS 
REGARDS
