Exam

Usually the cutoff of this course gets very high in DU.
If you belong to general category then it will be difficult to get into Delhi University with that much of percentage. If you are in any reserved category then there might be some chances. Search on DU portal the previous year cutoff of this course to get actual idea of which college you can get with that much of percentage.

Hello Vaishnavi, scoring good percentile in JEE Mains is no guarantee for a seat in c o e p. This is so since admissions of almost all colleges in the state of Maharashtra are through common entrance test called mht-cet. Of course there will be some seats in c o e p which may be filled up via JEE Mains, called all India quota seats, but how many seats and in which branch is not known at the moment. But with your present percentile you can perhaps get admission in a very good NIT in your desired branch.
Best wishes to you.
