Yaar i m here also in the same situation as u r in.
I scored 27994 rank in aieee(as it went very bad) and scored 810 rank in ip.
But i m sure of taking admission in ipu as i think i would get a good collge with desired branch.
I was also thnking of dropping a year as i was not satisfied with my aieee result but my parents are not in favour of it.
So i thnk taking admission in ipu and preparing for aieee nxt year would be a good choice(though i dont have any other choice) as if again i dont get any good collge in aieee nxt yr i would still have good collge in ipu.
