i think if u r from north india iit ropar would be best option and if from south iit hyderabad will be best option if u want to get core branchs.this post has rather turned to be confusing one bcoz of some idiots those who dont have much knowladge .
its true that new iits r now not very good option but better than many other think for a while can u expect a institute like iit to grow overnight , that cant happen becoz setting of new institute like iit will take time ,but if u join now at the time u will pass out these institute will be fully developed and would be some what comparable with old iits...
it-bhu is better option at this point of time but at the time u will pass out it wont be better option bcoz at that time most of the new iits would be fully developed and would and would be better in many terms ...
i told u iit ropar and iit hyderabad because of there locations ( bcoz location of a college counts a lot at the time of placement ) and how state govn. is taking iit for growth,, for eg. punjab govn. following the case of silicon valley,iit madras Research park is developing for techknow park near iit ropar for government academia industry partnership and similer is case with iit hyderabad while most of the other state govn. are not showing much interest ....
i wont say that join new iits blindly look out the campus,faculties and facilities carefully before joining ...
and permanent campus of this institutes is not much far away .....
if u want to take a non core branch in old iit and think that u can get core branch after one year so let me tell u that it woluld be very difficult let me site u an example let 40 student be in any core branch then only 4 student would be allowed to get into core branch and as u r gen. one 2 gen student would be allowed so u can expect how much difficult it would be to get core branch when all non core student are competing for 2 seats ....
so be wise before losing the tag of iit it may happen that u may regret for whole life that even after clearing
jee u r not an iitan or u have to study non core branch .........
