Much of my suggestion were to help you see balance. Remember that also includes the half hour that you spend on just enjoying the day.
For handling those 300 word questions... read the question first then go back over the passage. If you've PhotoRead it using Paul's method you've already covered it. The activation is then the question and superreading and dipping for the answer.
If you meditate or use the Memory Supercharger Paraliminal. Keep it up.
For the questions you need to do quick maths and work out at the beginning how much time you have available. Don't take the time they say you have work out a time for yourself.. 47 questions in 60 minutes = 1 minute per question and that should leave you 13 minutes to go back and fill in the missing ones. Reason you go back is simply incubation, while you're working on another problem the rest of the mind is still working on the answer to the earlier ones.
Remembering rules lie for true and false question... if the answer is only partly true then it's false, You cannot have as true an answer that is only partly true.
