In my opinion Sanjay Aggarwal Sir's CD will not be useful beacuse they are not original one they are recorded by way of wrong means I also have these CDs sound is not clear in these CDs. ANd these CDs are not available in market you have arrange them privately from your friends.
I am also confused about the book but al last I am satisfied with Paduka's book for Cost
If you want to go for self study then go for Padukas book for self study which is excellent for self study read al least two times every chapter with great concentration only then you can undetstand the concept other wise even if you get the cd they will not be useful for you.
After competing Padukas book you can go for SAXENA VASHISHT for more advanced level of practice
Please implement my strategy and see the difference.
