sir,due to low speed of internet in my area I could not correct disperancy in application..can u pls tell me what to do now

Hello,
You should search out for a place where internet connection is good.Go in a cyber internet cafe and try to remove disparency from your wbjee application form.
But as far as i know correction facility in wbjee application form was available between 26th January to 28th January.So you can't correct it now.
You can visit the below given link for more details:

Good luck.
