Online isca classes - jignesh cheeda sir

You may take the classes but trust me its not an alternative to  stuff you are supposed to do.The Classes will provide with you an overview.They stand alone will not put you through 40.

Buy self study guide on isca by manish valechha.  It is the best selling textbook for isca.  Dont waste your money. 

yes!! i have taken the classes online and found it really helpful... as i have hardly interest in studying comp. science so for me it was really good ... also i found his way of explaniation fair enough to understand..... and even the notes provided by him is also easy and are really helpful for self study.. so for my side... do join classes or take his online classes if u have very low interest in comp science !!! gud luck
