PhotoRead other books on the subject to help get the mind around the information. Focus on activating math book you need to work with. Activation is doing enough of the exercises to prove that you can do it.
When I was in high school I had a teacher who taught me that doing ALL the exercises is redundant . Pick a couple at random. Try to include those difficult ones. If you can do 4 out of the set of ten... go onto the next harder set. Only stay with a set of exercises if you are making mistakes. Once you got it right 4 times in a row it's fair to say you know how to do the formula correctly.
PhotoReading won't help you write the exercises faster as such it will help you understand it faster by reading the information supporting it faster.
