Hello Nitya, 

Considering your rank in the category of SC. There are some good colleges where you can apply. Some of the branches which you can get with ease are like CSE, IT, Electronics and communication, electrical and Electronics and instrumentation.

So last year the opening and closing rank of above branches of IET college for the year of 2017 was:-

Branch           Opening rank             closing rank

CSE                   274                            1224

Civil                     1496                          2025

Electrical           1960                           2837

So based on your rank you can easily get in IET Lucknow with above-mentioned branches. However, I would still suggest you keep your option open and apply for multiple colleges.

Now other than this some of the colleges where you can apply based on your rank are:

Harcourt Butler Technical University

Kamla Nehru Institute of Technology,

Bundelkhand Institute of technology,
