A simple strategy I was taught in my post-secondary courses, Is to briefly review what you had covered that day, just makes the lesson "sink-in" a little deeper. What I found worked very effectively was to just flip the text book, page by page, back to the beginning and as you do this every day, you will find you don't even have to read any of it again, because after a while, you remember everything on that page. I aced all the finals using this methid, and I found no need to do any last-minute cramming just before the test. I know it sometimes seems like a waste of time to page back every day for a year, but believe me, after applying this method, I found it really does work.
Don't think of it as part of your homework (I guess you can), but think of it more as studying a little bit at a time though the year instead of all at the end of the year and suffering the information overload when you need it most.
Good luck to all the students still writing exams, and congratulations to the ones that have completed them. Enjoy a safe and fish-filled summer
