Really have nothing subtantial to speak about this subject. It is more of procedure based. Just like Amitabh Bacchan in Kabhie Khushi Kabhi Gum (K3G) .."Keh Diya Toh Bas Keh Diya"
For the time being I wanna address just one crucial question which people keep on asking ......
Whether one should opt for tuitions for this subject?????
The answer is a very dicey one and there are a number of factors at play.
It all depends on your articleship exposure ..say whether you have actually seen a RG 23A and stuff in your life....This would determine whether the concepts of Cenvat Credit would strike you instaneously or whether you need a hypothetical set of numbers to drill into your grey cells these basic concepts.
Again your comfort level with theory is also crucial.Some people find it convenient to mug up if a theory is read out aloud and explained by a teacher.
Please try to strike a balance between the time you spend shuffling between tuitions in the last lap of your preparation and the benefits you reap out of the exercise. For self-preparation, the book by Bangar rocks ..although voluminious but still manageable !!!!!!!
Thats it for the time being
