Hello , 

As your query is you want to know when the classes of BHU BSc Mathematics group will start and you also want to know whether your admit card is still not issued to you so when it will be issued.

I would like to tell you that the classes for BHU BSc Mathematics group will start near about 15 July to 20 July in between and further talking about the admit card you need to understand this that admit card is issued only when you join the college or thereafter, before that there is no such concept of admit card or in between the counselling process or even at the time of admission so admit card is issued only when you join the college and then only it will be issued to you so there is nothing to worry about admit card.

Further if you need any other detail regarding the admission procedure or facilities you can please let me know in the comments section below we will definitely help you with that.

I hope your query is solved.

Thank you.
