Usually I study the material/look it over, then I write it down because I feel it helps me know and understand it more
Then I look over those notes once or twice a day when I have the chance. Throughout the day I will try to recall the whole thing by memory (speed through the parts that are easy) then review what I didn't remember
Start the cycle again the next day
It's a lot, but will really stick and takes no time depending on how much the notes can be
This has helped me but maybe it won't help others so kind of up to!
