I purchased the PhotoReading book and read through that and i was wondering if it is better for me to start of PR'ing material that is more interesting to me, or can i start off with my Calculus book?

I have another question... is this stuff good for images, like reading an art history book with many, many pictures and fewer words? or perhaps even sheet music?

I'm really excited to see how this system works for me and i'm hoping for great results!
