i need cse branch in any top college i cant get seat

It all depends on the entrance exam you have given and whether you have cleared the cutoff for your category. If you are looking for direct admission you must go and visit the private colleges and talk with them about this. There is no embarrasment, as everybody does this. I for sure do know that Galgotias University(not college) in Noida gives admission solely on class 12 percentages.There is no entrance exam. GLA University, Mathura is such a university as well. They have their own seperate exam which is very easy, anyone can easily crack it. There is no cutoff as well, it's either you pass or fail. If you pass you can choose any field you want. There is no need for you to panic, just explore the options that are available now.

I hope this answers your query.
