Hello sir! Iam in b.tech mechanical 1st yr..sir would you help me how to prepare for gate exam?

Hello sir! Iam in b.tech 1st mechanical student.sir would you help me how to prepare for gate exam?

i finished B,E mechanical at 2012.How long i can write gate exam……?

I was in need of some better results bt its given al the topics covered frm first yr to last yr pls. Tel me sm imp topics in mech engg. .as im in last so i cant coverd evrythng

gate 2013 syllabus or R09 regulation syllabus and some important website for the gate
