I'm finishing up my BSN on the path to the MSN. Just wanted to let you know that biochem and nutrition aren't to bad at all. The biochem had me scared so it was my first class. I was able to finish in 2 weeks. That's a lot of late nights and full days doing drawings and models...and of course watching the Thinkwell lectures, but I learned a lot and was really pleased with the class as a whole. Nutrition I gave myself a week, and that was completely doable. I work part-time and have 4 kids and this was in the summer...so they were all underfoot. I did buy a biochem model kit on Amazon which helped immensely with the 3-d models. Even had my kids help build them by handing me the oxygen or nitrogen molecule. You will do great in those classes, especially with your can-do attitude!! Best of luck!
