Ok..Let me tell you complete way of prep.. If you are looking for shortcut then i believe it is useless... But if you are looking for perfection, which is necessary for css, then i recommend you to prepare from foreign books. You should prepare cost accounting completely. Don't go for selective studies.. Please check this link.

Moreover, as you said that you don't have any know how about IAS..
then i have two files where you can prepare IAS and IFRS which are applicable in Pakistan. But I don't know how to upload them..
Before 2000 IFRS were known as IAS. But in 2000 IAS changes its name to IFRS and introduced some new standards. Pakistan opted very few of those IFRS. In Pakistan we are using IAS.
Followings are the main topics of cost accounting
1-Introduction and theory
2-Preparation of Cost of Good Sold
3-Job Order Costing
4-Process Costing
5-Inventory Control
6-Material Costing
7-Budgeting
8-Variance Analysis
These are the hot topics. Basically there is nothing new in Cost Accounting Syllabus.. Only Number distribution has changed.
