Dear candidate one thing is very hard to admit that even if you try to contact the colleges over phone, it is impossible for them to pick up every single call and respond to the queries, now there is an alternate way, where you can send a mail to their mail id provided for enquiry or for any specific information you can visit their website and read their information brochures. You can follow their notice and announcement board for any updates. Hope it works,

Good luck!! Follow this for more information
