Dinesh Madaan(self stdy) is too gud.........So, I believe he mite b gud teacher too(though i havnt taken coachin 4m him)............W8 for suggestions by others too.

Book of Maneesh Valecha is also good for self study but dont know whether he takes classes 

Thanks a lot

my advise is to go for module also along with above said books..as these books lack some parts..

i don't knw abt teachers but if u can find Mr. Ravi's article on how to prepare for ISCA, then it will be very gud...it is very gud one....just read it....Mr. Ravi himself got 69 by self study in ISCA....

Thanks a lot sahil
