Overview
A good test of your background on the topics related to this course would be to review the materials in the open educational resource EGEE 102. If you are comfortable with the concepts in EGEE 102, you should be in pretty good shape to tackle EME 802 (i.e., unit conversions, general energy terminologies, use of algebra...). In particular, if you are coming from a social science background or if it has just been a while since you have put some of your scientific or mathematical skills to the test, this page will help provide some additional resources to help get you up to speed. Feel free to contact the instructor with any recommendations for additional topics to include on this resources page, or with references which you would recommend for others.
Mathematics/Background Materials
Starting from the basics, if you find you might want to refresh your skills in the rules of manipulating algebraic expressions, the Khan academy really covers all of this from the very basics to the very advanced here. It will be absolutely necessary to be comfortable with algebra in this course at a minimum.
Additionally, if you haven't had calculus before and want a quick idea of what it is all about, here are a few videos from the Khan Academy that will give you some basic information to get you started (it is reiterated in the document above, but the videos provide more examples). We will touch on calculus in a couple of lessons, so if this is well out of your comfort zone, it will be ok; just hang in there and give it your best effort.
