Hey aspirant!

If you have obtained 70 marks in the CMAT examination and not 70 percentile score, then, too be honest, your chances of getting any decent college is extremely small, leave aside the government colleges. However, if you wanted to enquire about 70 percentile and have mistakingly written 70 marks in your question, then kindly mention it in a comment and I would surely try to help you out in that case. Now, since your marks are not so good, therefore, it is advised to appear for other management exams as many B-schools accept other exam scores as well for admission because at 70 marks, you have chances at a few colleges only based on previous years trends.

If you want to know about the colleges which you may get based on your score and previous year trends, then you can refer to the following link
