MORE HELP!

Tyler DeWitt (not related to the Adelle DeWitt of Dollhouse) is a former high school science teacher and current Ph.D. student at MIT who was recently featured at a TEDx Convention giving a talk about making science fun and engaging for students. He argues about eschewing some of the exacting jargon in typical public school science textbooks to make concepts more accessible to teens.

As a part of his vision, he (like Salman Khan) has produced a series of videos to assist students in learning different concepts from chemistry. His YouTube Channel is chock full of short, concise videos that help break down practice problems- especially for the exam tomorrow! I would have had this up sooner but only discovered it today! His conversational tutoring style is a lot less filled with "um's" and other fillers which makes the video much easier to follow. Sometimes they're even shorter than Khan's so that he's not stretching to artificially fill up some required ten-minute benchmark.
This could help make or break some of the problems you'll face on the exam I would spend a little time searching through his topics to beef up on areas with which you're not so comfortable. This isn't nearly as cute or entertaining as Minute Physics, but the audiences are really different crowds.
That said, click over the links and this may help guide your learning this evening. Don't stress out!
