Narsee Monjee College of Commerce and Economics, Mumbai has a very strict attendance policy of a minimum of 75% required overall. The college is however very strict for attendance and you need to follow the attendance rule. There is no way you can escape it.
However, the college does give some relaxation to students by bringing down the overall attendance to 50% and individual subject attendance to 25%. I would suggest you don’t ever fall below this mark. You will have to attend classes even at 7 AM in the morning to maintain at least 50% aggregate and 25% individual subject mark. If you are lucky enough then you can get away with proxies as I did. But you should not take this for granted as some professors are very strict about this.
Also, there is no special rule for those pursuing CA and CS courses along with attending the college.
I would say that please do not get scared of the 75% attendance rule. The professors and the seniors may scare you with this but it eventually comes down to 50%.
