Ca final cost

Tamanna (Qualified CA) (164 Points)

02 March 2015  
I will be appearing for CA final in May 2015. I had taken tuition for Cost a year and a half back but now when I'm about to do things on my own I'm not feeling very confident about the way things were taught in class. Even during the classes I was not comfortable with the way the subject was being taught. Costing is a subject which I considered to be one of my strengths till the IPCC level but now I'm really lost as to where to study this subject from. I am not able to study from the class notes and want to know will doing the sums from Institute Mat and PM be sufficient for this paper as I don't really have a lot of time left. Please help.
