i got 52% in pcm in 12 by cbse and i have service man or army quota so which collage is best for me ?
If you're asking about placements or anything, you need to mention the board of exam you've taken, and which college you want to join. After that I'll let you know all the possibilities.
I guess, you don't have any options now. But for now you can pay donation fees and you can opt any universities now. But the fee's will be definitely high.

its very bad i know ....
Try next year and study well.
All the best.
