Exam

Dear,
Fee for MBA or PGDM programme varies between Rs.7 lakh to 21 lakh.

No, it is not necessary. Only if you want to get an IIT, NIT, IIIT, etc. you should write it.
These all are government aided colleges (central government).If you want to study in private universities like VIT, BITS Pilani, SRM then you have to write their entrance exams. They never see your JEE marks

You need to score a minimum of 50% in class 10th.

Your Diploma doesn't matter for JEE exam, if you qualify JEE Mains then you have to study from first year your diploma will not consider for JEE, but you got the benefit of OBC certificate.

Hello Gulshan,
There are some people who are always offering free coaching. However the student needs to have good academic performance. Super 30 of Patna & similar efforts at a place near Pune. I am sure in your own state there will be dedicated teachers. You need to find them. That's all.

Some of the engineering colleges will not offer admission to the students with supplementary papers but some may. You have to confirm with the college before admission. So, for more information please contact the college admissions cell.

If you want to get admission in Maharashtra by JEE score then you have to score a good rank.
