Dear,

In order to get VJTI through MHCET you can give mhcet in pcm or pcmb. Both are considered. Now, if you are planning engg I would suggest just take pcm because pcmb would cost you 4 subjects and its kindof burden to students. If you think you can handle all subjects go for it. But talking about your question you can take anything between pcm or pcmb.

Hope this helps! Good luck!
