With learning Physics, I found for me going forwards and backwards on every page was an amazing help. but eventually it got me bogged down. I try nowadays to combine several methods of learning. One way is to listen to lectures by experts that are now accessible on the internet. In years past, there was no access to anything like this unless one was enrolled in a university. I also hold strongly with the path of learning of Rav Nachman of saying the words and going on with no review until I have finished the whole book, and then review the whole book at least four times. {This comes from the Conversations of Rav Nachman of Breslov number 76. It is also hinted at in the LeM of Rav Nachman vol. I, chapter 11. } [The forwards and backwards approach helped me get started, and also to get through my subjects at Polytechnic Institute of NYU.] [The source in the Gemara in Tractate Shabat page 63 and Tractate Avoda Aara page 19a]
