Thank you very much for the tips. Yeah, I know what you guys say but I don't mean that I am gonna slack off my reading after I master the Photoreading. You know I am willing to take as many APs as possible so that I can save both time and money in college. 14 APs are tentative. If I under stand well on those AP subjects I am planning to take, then I will take more, but if I don't then, obviously I will reduce. I have been working for AP studies for 10-15 hours a day, and I become dead tired by Friday and Saturday. I even reduced my sleeping time from 6 hours to 4-5 hours. I hope Photoreading can boost my speed and comprehension so that I can have more breaks and rests. I am willing to work hard but I dont wanna work like a slave in a death camp. Ok, I understand that this is not like a magic overnight. So how long did it take you guys to approach both speed about 1000-1500 wpm and high comprehension from the day you bought the photoreading? Thank you for the replying
