I'm the class room student of Ramanasri Maths optional institute. I even went to demo classes the other institutes in Delhi .But I didn't satisfied due to lack of attention in classes.I found really good environment in classes of Ramanasri sir. Sir is very supportive .He teaches with basics, examples even the tough topics like Modern Algebra, Real Analysis , Fluid dynamic, Dynamics and Statics. Sir is the best teacher in IAS Maths optional. Even my time was saved they completed within 6 months I have attended only 1 batch,even some of my friends completed with in 3months,they attended 2 batches. Now I'm writing the test series for revision. Sir gives the guidance even during revision. This is the best institute for Maths optional.
