People learn best by both reading and hearing what is taught as well as both speaking and writing it. It helps so very much to reinforce the information in your head and commit it to long term memory.

Likewise take breaks when you study. In general it’s a good idea to take a 15 min. break for every hour you study. More if you find yourself drifting.

Sleep when you need to. You will retain very little if you are studying when you’re too tired. The same goes for eating.

Take the time that you need. Plan ahead and don’t pressure yourself to get it done by such and such a time. It takes as long as it takes. Adding pressure will only make it more difficult.

If you can find something you really like about what you are studying. It doesn’t matter what. If you like some aspect of it it will be very much easier to learn.
