1. Teacher Time: If you are lucky enough to get some one-to-one teacher time, it is important to make good efficient use of it. When you are studying alone, use post-it notes to note your problems and stick it in your book.
2. Understanding is not necessarily learning: Often students think that once they see the teacher do a problem on the board they found difficult (and understand how the teacher did it) then they have learned how to do it. This is not the case. It is important to practice it again later yourself!
3. Only do the questions you can’t: This seems odd, but basically don’t waste your limited study time doing questions you know you can do. Push yourself with the hard ones, the ones you think you can’t do. You might surprise yourself!
