Dear Student,

If you are pursuing diploma and you want to continue it in BITS pilani then it's a NO, but as for taking the entrance exam you have to pass 10+2 from a recognized board with aggregate 75% marks in PCM and total over all marks of 65% in all subject.

And if you are a diploma student with no 10+2 passing mark sheet with marks specified above I am sorry but you can't apply for BITS pilani entrance exam.
