B.Tech Computer Science and Engineering

Yes, Amity-Noida is very good for B.Tech in CS. Apart from that, this university will play a crucial role in your overall development which would prove to be of great help afterwards as this university not only lay emphasis on academics but other things also. But please do not, I repeat never ruin your academics as it will create a huge problem for you during campus selection. Apart from this, take part in all the activities like debates, sports, etc. It will definitely develop your personality, communication skills, attitude and what not. The teachers are really helpful there. You just need to make a bond with them. And if you study well, you can get 50% and even 100% scholarship. And the last thing, don't worry about your placement. Just concentrate on your studies and take full advantage of sports and various types of competitions held there. You will definitely enjoy your college life.
Good luck.

In case, you don't get your desired college, don't settle for something mediocre. Instead of settling down for some mediocre college, it would be better if you try for some good private university. Many reputed private universities are offering B.Tech CSE. They have different criteria for admissions. Some offer admission on the basis of JEE scores, some offer admission on basis of their own tests and some offer admission on the basis of both. Some even offer direct admission on basis of class 12th marks. Some of the universities also offer scholarships on basis of your performance in class 12th or JEE or their own tests. You can check the details of any of the reputed universities like VIT, Lovely, SRM, etc. All these universities have a wonderful infrastructure and world-class facilities to offer to students apart from good placements.
Good luck.
