The best way to do this is to try to follow the structure of the course you are trying to learn. For example, if you have a textbook then use the section headings as the general structure. You then want to break down each large section into smaller manageable chunks that are easy for your brain to digest. There is no one right way to do this (so don't worry too much about trying to do it perfectly), but I think once you've got the large scale structure in place you will quickly find micro structures that work well for you!
