As per my knowledge, I think it is Diploma base, because a student with Diploma has more practical knowledge than a class 12th base engineering student. That's why companies hires Diploma students, because they are even ready to work for less salary.

BBA in event management will be a better option since a degree is a step above the Diploma. It has a greater value and also event management is a growing field & has a lot of scope. You can earn a handsome salary in this field. So, it is advisable to do a BBA management degree.

Hi, PCM marks of 12th do not have big concerns for your engineering admission. Your MHTCET score (142/200) is outstanding, so you are genuinely eligible for engineering admission. Good luck.

I'm not sure about it but yes as per your quota you may get admission.
Best wishes.

Yes, you can become but only after clearing the written and physical tests. So, start preparing for it. Good luck.
