Work In A Group . A group can be a strong support system and another time saver. It is important to have someone to talk with about any subject, especially math. Verbalizing confusing areas can help clarify what you know and what you don't. Tutoring someone else is a very powerful learning device.
Good notes are important, so bring plenty of paper to class.
I suggest using a three ring binder, so that you can add paper when necessary. Don't worry about penmanship and spelling. Since we all make mistakes, write with a dark pencil or an erasable ink pen. Write down everything the teacher does on the board. If the teacher says something important and doesn't write it down, make them repeat it.
