Diploma

Dude the best college for you will be LPU.You can also get it from COMEDK colleges and colleges in Noida. They offer distance learning option in their college.

Hello Aishwarya,
Completion of Diploma in computer engineering does not make you automatically qualify for financial e arts courses. Fundamentally, if you have done diploma after 10th then you can do only those fine arts courses which have 10th pass as criteria. Same logic for 12th.

You can try job through RRB for Railways, SSC, State jobs etc. You can take training from NPTI, For design courses from any CITD ( Central Institute of Tool Design) etc.

Your admission depends on your score in CMAT, MAT or CAT exam, not on your 10th or 12th scores.

Your score is moderate to take admission in Pune University because in Diploma, most of the students got high marks and no. of seats are only 10%. So, the cut-off list to take direct admission is quite high. Also, if you are other than University of Pune, then it is even hard to get admission. Kindly apply in MIT/Singhad/Bharti college.

After PG Diploma, you have to join engineering further with same mechanical engineering trade and get degree from engineering colleges which are highly reputed because in Diploma, many student got more than 85% marks and seats for Diploma candidate in engineering colleges are only 10% as per central arrangements, so the chance to get good college is quite good but if you get a good college like COEP, VJTI, etc. then it will be better for you.
All the best.
