i have brilliant 1 year old material.i want to buy correspondence of either fiitjee or  resonance.which one i should buy .mention both's positive as well as negative points.

in my view brilliant's material is sufficient but if you really wanna go for another then you should undoubtedly prefer fiitjee over resonance.

I have not seen resonance but I can assure that fiitjee study material is rather gud & of high level particularly maths section .rate me if useful
