yaar, you should come until mid of November because i think from december they will start with the interviews. and the earlier you come the better it is from the prpaaration point of view, if you could easily manage to come by the mid of november thn do book your seat in advance. Atleast in my opinion you should be here until 24th Nov.
but look at yur priorities. And by the way you did not respond to my e-mail.....
yar u always forget kukikhel.
