Is some good government collage offers direct admission.?
Respected Sir,
IISc is he best college in India currently and there is no direct entry. You need to earn your way into it either by KVPY , NEET or JEE advance.
And for Tamil Nadu Colleges ,you need to apply for TNEA , a counselling based purely on Board marks.
And for private colleges like SRM, kindly contact the college people itself. They would help you for direct entry.
Hope I was able to help you.
