Preview and go through a new lesson before class. Pay attention to what is said in class and take mental and written notes. Whenever you take notes, you should not only use your hands but also use your brain; you should keep yourself brainstorming. Ask questions. This is most basic way to learn. Do not be ashamed or afraid to ask questions. There are no stupid questions. As the saying goes "Those who ask may be a fool for 5 minutes, but those who don't will be a fool forever." Review what you learned after class. If necessary, work at it until you know the required work by heart. Underline sections of your notes or portions of your text that you don't understand well so you can raise your problems and discuss them with your classmates and teachers in class.
