Dear Shweta,

I hope you are doing well !

As per your query it is wrong if you are wants to take admission in BCA and mCA then Yes , you can apply for the BCA undergraduate course duration of 3 years but right now you will not able to take admission in MCA because it is a master course and if you wants to join in master course so you have to complete your Undergraduate course then after you can go through the master .

But at a time you cant appear both of course .

I hope it will helpful

Thanks
