Both are not up to the mark. Try to search for another college. There good colleges like Christ University, Bangalore, MS Ramaiha, Bangalore, CMS Jain, Adarsh Institute of Management, Bangalore etc.

Here are the colleges:
Dr. Harisingh Gour Vishwavidyalaya, Faculty of Biotechnology (Sagar)
Awadhesh Pratap Singh University (Rewa)
Barkatullah Vishwavidyalaya (Hoshangabad)
Devi Ahilya Vishwavidyalaya
Jawaharlal Nehru Krishi Vishwavidyalaya
Jiwaji University (Gwalior)
ITM Group of Colleges (Gwalior)

Its hard to say because different colleges have different requirements, they might not recognise your qualification or they might evaluate your grades as per their norms and check. it is best you personally contact a few universities, email them and they will guide you.

Firstly, you have to learn GK daily as there are 50 marks question from General knowledge/Current Affairs.
Try to revises question of reasoning from the book of MTG or TMH.
All the best.
