Here's the deal on extra credit. The most effective way to take notes is to sit down sometime shortly after class, review and rewrite your notes. Take the sketchy outline notes -- the name, date, abbreviated definition sort of thing you write during class -- and put them into what can be called a narrative form. Write out your notes using whole sentences, and organize them into paragraphs. By forcing yourself to think through the gaps in your notes, you'll write out the relationships and comparisons you forgot to put into your notes. This does take some effort and about an hour of your time, but it is worth it.
I will give you one-point extra credit for each lecture "write up" that you turn in. But there are some requirements:
While one point isn't very
much, one point for each lecture is worth almost an entire letter
grade. Don't wait until the final week of the semester! The real
advantage is that you’ll do much better on the exams.
