Diploma

Hello Devanshu
I suggest you to go through B.Tech as it is good and has more demand in near future also.
If you not applied for any B.Tech college then don't worry there are many college which takes admission through 12th marks.

Bother, why you want to do Diploma if you have done +2? I would suggest you to do B.Tech instead of it. It has more value than Diploma. Moreover, you can save two years by choosing B.Tech.

Hi Riya,
Although you can, but it is advisable for you complete your class 12th in any of the streams (mainly arts and humanities) to pursue a course in acting. You can in fact pursue your graduation in acting or BJMC which will make you an actor and a graduate at the same time. Completing class 12th will also make your career more secure than other Diploma courses.
All the best.

Yes, Jain University has super facilities in the aerospace branch but placements are not that good. Around 4-5 students get placed out of 10 and remaining go for Masters.

Universities are approved by UGC only. Technical Colleges require AICTE approval and registration. So, there is no problem with your Polytechnic Diploma. It will be considered valid for higher education.
