You will have to understand the flow of the processes as they relate to each other. Memorizing the processes will help, but the test will play on your understand and grasp of the concept. Read the ITTOS and see how the inputs and outputs play, this should give you an indication of which process you are in. Also, on the test, pay attention to what is being asked, this can be tricky, but very doable.
Place some effort on seeing how the inputs and outputs work together and where they go or come from.
