GATEFORUM TRICHY had best faculties for GATE preparation, most of them have been either PSU employees or eminent scholars.
Test Series seems more relevant to GATE Pattern. If you are from 3rd or final year of your B.Tech/B.E. then its right time to kick start your preparation.
I have joined GATEFORUM TRICY in very start of my final year and I did clear and now I am pursuing M.Tech from NIT TRICHY
