Ipcc classes - what is best?

Dear Friends----?

I attended ipcc classes in many places - each subject in one place....and some how cleared my ipcc  attempt .

I wanted to put my brother into ipcc. I have asked him to take all subjects classes at same place / same institute. so that it saves his time. I saw, gurukripa website, prime website, MT educare. All is good.

But people are advicing to attend accounts in prime, tax and cost in gurukripa.

Is it not worth to attend all subjects in same institute? - Gurukripa has IPCC full time coaching --- how abt attending it?
