Writing "Cram Sheets" for Math/Science Classes... I like to write "Cram Sheets" for Math/Science Class that include my common mistakes, important notes, and any extra information that my textbook does not accentuate or simplify. I like them to be neat and tidy (and hopefully digital so I can reproduce them) so I'm debating as to whether I should use MathCad, Mathematica 5.1, or TeXnic Center to type them up. Which one do you think would be most useful and efficient and why? Also, if you guys have any other strategies or tools you use to help you through your Math/Sciences courses, please share! Some examples include use of flashcards, voice recording, etc.
