Hi aspirant, you have done well. But the cutoff for CSE at MMMUT is high. 

Last year, I think the GNOP cutoff was around 381 for CSE. 

This year, I think it will be a little lower. So you might have a chance. In my opinion, if you have no better option, apply for counselling and see how it works out. You might get it.

Hope this helps. Regards. Good luck.
