If you can, take something else, if you can't, consider taking a bad grade and focusing on something else anyway.
The suggestion in the article is awful. It is far more important to work hard at concentrating for long periods of time. All this method is doing is conditioning you to be scatterbrained. We get enough of that already.
But spending a few hours/day in the library the week leading up to an exam never killed anyone. I kind of enjoyed my time alone to pore over my semester's notes. It was meditative.
The advice in this article (take notes like study guides, study them over 2 10-minute intervals each day) is harmless enough. I just don't like the presentation.
I always kicked ass in courses where I immediately scoped stuff out and divided it into the smallest possible chunks.
The trouble with a lot of todo programs is that they make doing this with your tasks kind of a pain -- so you just end up with a single task "Do $massive_project" with a due date. I'm hoping to solve this with a side project.
