Inquiry abt JB Gupta sfm classes????

Can any one suggest whether jb gupta classes for mafa/sfm is gud or not ????

Also if sm1 hs alrdy taken classes fr him ,  pls lemme knw dat whether his notes suffice fr the course. .n are his coaching style modern enuf given the pratical approach ca final exams are held ???

Actually the timings of Mr. Ashish Kalra sir dont suit me , and seniors are of the opinion that makkar sir's attention is only on giving the notes and not on onceptual clarity. .

I hav 2 decide within a day or 2  . .

i m very confusd . . lukin fr help . . pls suggest sth asap. .
