Hi Benazeer, I have not covered Corporate and Partnership Accounting in my courses. For Management Accounting , you can refer to another course prepared by me, titled as Summary of Management Accounting. For BEP, you can refer to another course, Break Even Analysis. Cost Accounting is not that much important, only 2 3 questions are asked. :)
