Advance management accounting

There is nothing wrong with those outdated classes, do them first and then buy sanjay agarwal latest book....there will be no problems.
  In fact this November most questions in AMA actually came from the classes you called outdated...so never think that those classes are obsolete and of no use now.

Refer old classes, than purchase latest edition of any author.

Dear ,concepts can never change. The varieties of questions may.So If you have with you so called 'obsolete material' of Sanjay Sir, its totally wrong....That is sufficient if you devote time to the classes(recorded) as well as his materials. Yes.........you can go through recent PM .......to gain confidence and be updated.But I will personally suggest don go for any book if you have Sanjay Sir's material;like padhuka...and others, you may be confused.........Just avoid Padhuka, Bangar etc who are advertising through this platform..............No More.........and just don waste money
