Ipcc costing and financial management

Hello everyone,

I am Charitha from Hyderabad. I am going to attempt IPCC in may 2015 both the groups. My concepts are really weak in

COSTING: Overheads, Non Integrated Accounts, Process Costing and Joint products and by products

FM: Financing Decisions, Investment Decisions.

So can anyone tell me how to prepare these chapters as they are very important from the exam point and if possible can anyone send me the online videos or tell me where can i find these videos!

thanks
