sooooooooooo,

gate,,,,,,,nw m cuming for breakkkkkkkkkkkk u

LAKRA IS

COMING, U BETTER START RUNNING

ye kya halwa hai ki esse koi bhi break kar de

i will coming to crack gate 2013..........

gate is only for me to cross it ....

can anybody tell me that I completed my B.tech in EC but my interest is in Electrical. so can I apply for electrical GATE......please reply me....thanx.....

gate2013 this time i will fight with u..............don't be smart .............now i am front of you.........

Vivek joshi hai kya kaminey

Agar hai to ander lele mera

yes you can appear for electrical but that wud be litle difficult to go through whole syllabus.

rather you can appear for gate in EC and then continue ur post grad in EE

pheewwww.........

m nw in 5th sem...can nebody suggest me regardng d preparation of GATE...wich buks gona help me most??
