Thanks for all the advice. Nietzsche is definitely dense, and even he recommends reading it slowly. I'll try reading some background works, just for photoreading practice.
For the most part though, I can understand his works if I read through them slowly and carefully, often combing it over several times. Next time, I think I will Activate it multiple times per chapter and then superread. I think in the end I will be faster than other people. Some kids in my class often spend 5-6 hours on an 80 page assignment.
Thanks for the tips.
