Hello friends, My younger brother studied in resonance in kota last two year and he creacked iit jee advance 2017 .resonance is very good in jee field but not excellent in the medical field but perfect for the iit jee advance and iit jee main.if you thinking for iit jee advance then you have to give at least 2 year + 1 and + 2 then you can easily get select but if taking only one year coaching then it very difficult to creak the iit jee advance then I will advice you to prepare for jee main not for advance.resonance if very excellent in the both the areas main and advance but the thing matters is your hardwork.if you any query then contact me on intagram sachin7604
Thankyou
