Hello Gaurav Singh Rawat. Thanks for contacting Careers360 and we hope we will be able to answer your query. 

First up, ask yourself this question: I have got so low marks in my boards? Will I be able to cope up with such a rigorous schedule if engineering?

Also, note that there are so many colleges that you can take admission in on the basis of the management quota. Among them, some of the top institutions are:

• AMITY;
• SRM;
• LPU;
• Sharda University, etc.
