Hello Jitender, I was also selected PCMB group in class 11 th and 12 th. So i think I can answer this question very well. First of all there are no any disadvantage of taking PCMB. but it has advantages more. Means you are putting 2 ways for your career. If you are still confused about your career, then you got more two years to choose , depending on your interest. No of entrance exams eligibility increases due to choosing PCMB.

You can get more knowledge of one additional subject for two years.

I hope it will help.

Thanks.
