For thrid question, I would recommend a software with which you can practice something to remember based on the "forgetting curve theory". People call it 'flash card.' "Anki" is one of the free softwares you can do effectively.

It depends on your natural way of learning. Do you know if you are a visual, audio, or kinesthetic learner? Depending on your preference some methods of learning will work and others will have little results. There are other factors of your personality that can determine your best method of learning. Such as your independence or dependence, competitive nature or collaborative nature, avoidant or participant preference. As an example I'm mostly a visual, independent, collaborative, avoidant learner. So my best method is to study alone or with a like minded partner using pictures, worksheets, slides, and video media. If you figure out which type of learner you are you can find specific ways to learn in a more efficient manner. I also recommend taking note of which learning styles helps most while in class with different teachers. (If you're in college or school, of course)

thanks so much :)
