Helo champ, dont lose hope.Just remember one thing, everything happens for a reason. If you didn't qualify iit exam, dont wory u can go for private colleges . There are many colleges. You can also fill scholarship exam for these colleges.  If there is a will,there is a way. You want to clear iit so do it. Have faith in yourself and you will do it. If somewhat it doesn't happen than dont worry god has better plans for you . 

If you didn't clear iit, you can do btech from private colleges, you can also drop a year if you really wish to do so. Otherwise the best option is to prepare for govt exams. 

Believe in yourself and yes everything happens for a reason
