Appreciate that you are preparing for a test and that you want to pass it. However, the reason that we go through these emergencies is because ANY of them might really happen - so you need to know all of them, ideally from memory!
How many regular GA pilots out there really practice the full set of emergencies on a regular basis? How many are comfortable that they would get it completely right every time? If you can't do it in the relative calm of a training/practice situation, you won't have much hope as and when it really does go pear shaped.
