I attended the modern algebra module at CHROME IAS . The topic was covered very lucidly. Individual attention to students, commitment in terms of sticking to time schedule, focus on writing style in exam were some of the things i found very good at the institute. I cant say more about the teaching than the fact that Sir taught how one should think while approaching modern algebra questions(those with any exposure to this mountain of a unit would understand how important this becomes in abstract mathematics). Would recommend chrome ias to anyone preparing for civils with maths as optional.
