Taking organic 2 and physics 2, commuting two hours and studying for the mcat does sound like a lot no wonder that you are overwhelmed! my hat is off to you. I had the AO and hated it, way to goofy for me with sound effects and other type of goofy things. Some folks loved it though so go figure. I think that if you go on the EK webpage you can get a sample CD although you may have to purchase something I do not remember. Their prep materials are just awesome (aside from AO) and I used them along with TPR prep materials. Worked really well for me....good luck!
