For BCMSN exam I did not attend for any classes and did not do any labs. But strictly speaking this is not good. To me BCMSN is not that much important to me. That's why I did not put that much effort on that. And that's the main reason why I got very low marks in that exam.
The concepts in the BCMSN was important to me.
I don't have much experience in BCMSN to share with you.
