It's not a great deal if you want to remember anything just you have to concentrate at you r subject you want to learn
First thing you must understand what you r studying don't just go on reading[ratta]
Then with calm mind just see the answer in a silent place try to understand what's there and you can use dictionary sor finding difficult words
just study for 2-3 hrs not more than that a day
you will see changes for sure
If the answers are big then speak them loud and learn. If small then do it your way! The best way for all types of answers is to understand them and so this helps good in learning!
Just Read two times and speak them loud! Try to understand too
