Some very good advice for college calculus students. Read this carefully and do as it suggests.
I used to ask my students to read this whole page at the beginning of a course, but it's grown rather long for that. Still, you should take a glance over this, and read at least some of it carefully. You'll do better in your math classes because of it. I encourage you to pay particular attention to the sections: bad handwriting, all of the algebra errors, stream-of-consciousness notations, and going over your work.
