Hii Gaurav!

You should not think like this that you are an average student. Every student has an unique quality or talent in them. No one is average. It's just that you need to know well, the field in which you are good. Now talking about BTech courses, you can opt for any of the wide variety of courses offered all over India. Let me list some of them -

* Chemical engineering

* Petroleum engineering

* Information and communication technology

* IT

* Biotechnology

Etc., Look for your field of interest and then decide and trust me, you will be awesome. For more details refer the link given below -
