Need Help with AFM!

I have my AFM exam on the 6th and because of work, all I have been through till now is investment appraisal but in detail (did almost all investment appraisal exam kit questions). I understand that what is left now is Risk Management, Mergers & Acquisitions and Business Reorganization/ Reconstruction. Am I too late to start these and is there a specific order I should be tackling these topic considering the amount of time left. Also any lectures/ material for each of these topics would be greatly appreciated. Please help a brother out.
