Offline Coding classes suggestion in Gurgaon/Delhi?

Can you plz suggest me some good Offline Coding Classes in Gurgaon, OP is going to start B.Tech in CSE in about 2 months (kaha se? pta nhi abhi). I prefer Offline over Online. I live in Manesar area but I also don't mind going to Delhi if they teach really good and fees are nominal.
Thanks and I wish u a gud day!
