If you do the rapid reading step for novels then you'll be at least as good, and most likely better, at the specific questions. For textbooks you'll be light years ahead of your classmates if you spend 5 to 15 minutes with the chapter before a lecture. That's for technical stuff like bio and physics. History textbooks are awful--you have to photoread, superread and dip, and THEN you have to rapid read. In the end, however, that's still about half the time investment than normal reading.
