Da, da, dun!

The countdown is on until my exam. The expensive one. The one I really don't want to retake. The one I need in order to work. Yeah, that one. I've been studying off and on but not consistently. Being out of town all last week meant zero study time but I'm getting back on track this week. I'm trying to look over a little of everything. Sometimes I'm not sure if learning about respironics oxygen concentrators is more important than learning about medical jargon and definitions. I figure as long as I go over literally everything, hopefully most of it will stick when it comes time to take my test. Hopefully right? LOL
