imran: hi i want to know how many month to prepare for IAS exams

THERE IS NOT FIXED PERIOD OF PREPARATION OF IAS EXAM. BY OBSERVING ALL AROUND OF YOUR WORLD ACCORDING YOUR SUB., YOU CAN CONTINUE YOUR PREPARATION. THIS IS BCOZ. EVERY ONE HAS IT'S OWEN TIME TABLE. BUT FOR REGULAR STUDENT @2 MOUNTH IS ENOUGH( 4 HOUR PER DAY)

Since your question is to Brilliant Tutorial, they have first right to answer. I will suggest that a fair preparation will take 1-2 years.
