Hi,

To get PCM, there is as such no minimum percentage. The criteria is determined mainly by schools in which you wish to take admission in. Thus, you can go for PCM but it entirely depends on the school you want to get admission in, On addition of this, if you wish to join a dummy school, there are a lot of educational institutes that offer students an option for dummy school, you can directly contact the educational institutes for that. Also, you can opt for NIOS which is a option for candidates who wish to give exams as a private or open candidate.

You can ask questions in the comments section. I hope this helped you.
