I have to disagree with razor on the test aspect of your question. Rapid reading and Super Reading is PERFECT for tests!
Here is why, the main goal of learning anything is to have a goal and reason for reading it right?
With your tests like the SAT look over the questions for the passage you must read to answer them. There is what you are looking for, Super Read them Dip and Rapid read the areas of the text where the answers are.
After reading through the questions then rapid reading and super reading the text you will find that the answers leap up at you saving you time and finishing the test early is great for your social life. Though your classmates will hate you. 
The Photo Reading system is totally different than anything out there it is based on learning, using your WHOLE MIND, to absorb and learn anything incredibly fast.
It is NOT a magic bullet though and YOU have to actually learn and use the system to recieve any benefit. Can't just read the book once and say I got it and never use the skills taught.
The book is great my suggestion since you are in school and I assume plan on going to college is to invest in the home study course as well, the book actually comes in it.
Photo reading is different I grant you, many don't really understand it's true potential, but it is an excellent program.
Speed Reading students who switch to the Photo Reading system have for some reason more difficulty with the transition than those who do not. Not sure why, maybe the jump in speed isn't as great at first than those who read say 200-400 wpm instead of 700-2500 wpm?
Not all the techniques in this system are universal, in that the Photo Reading step is great for learning text in text books and books on every topic imaginable but it sucks when used for sats or other tests. It wasn't designed for that use, but Super Reading and diping with rapid reading are great for it as long as you have the purpose in mind which is to get the answers for questions 1-20..
Basically Super Reading and Rapid Reading ARE forms of speed reading! Just using these two techniques will increase your over all reading speed greatly.
