How can I get a good grade in a difficult subject?

Many times when you are faced with adversity, the first thing you must do is to rethink your strategy. Try to prepare a well-focused, positive strategy. Number one, are you taking notes in class? It's one of those simple things that sometimes we forget about, but good notes go a long way, especially when you're studying for the test or the assessment that teachers are about to give. Number two, make sure that you're understanding the material and your notes. If you're not understanding the material that's being presented, and your notes don't make sense, talk to your teacher and ask for extra assistance.
