Hi aspirant the fact is you have really a good rank in UPSEE exam but I would like to clear this thing first that still it is not sufficient which can take you to KNIT, Sultanpur or not all but many other Government Institutions untill and unless you have any reserved quota. But you can take admission in any of most of the State Rajkiya Engineering colleges. So i'm mentioning some of the Government/Public colleges excluding Rajikiya Engineering Colleges as well as some good private colleges into which you can get into with your favourable branch;

• Indraprastha Institute of Information and Technology, Delhi
• Dr. Ram Manohar Lohia Avadh University
• Veer Bahadur Singh Purvanchal University, Jaunpur
• University Institute of Engineering and Technology, Kanpur
• Pranveer Singh Institute of Technology, Kanpur
• GL Bajaj Group of Institutions, Mathura
• Noida Institute of Engineering and Technology, Noida
• Ajay Kumar Garg Engineering College, Ghaziabad
• KIET, Ghaziabad
• United Group of Institutions, Allahabad

Etc.

Moreover you can also take help to predict your own college by yourself through Careers360 UPSEE College Predictor tool(link mentioned below) according to your rank in any category;

Good Luck.
