It'll be over before you know it. The hardest part of Anatomy is the beginning. Once you learn the muscles & bones, it's much easier to move on to the other systems because it all builds on the foundation you set. Just think: having a heavy study load now will prepare you for nursing school later when you'll REALLY be going at it hard.
I'm taking 17 credits this semester: Physiology, Microbiology, Microbiology Lab, Pharmacology, Intro to Health Professions and Human Growth & Development. There isn't a time where I'm NOT studying...LOL
But if I can make it through this...then I feel like I can handle nursing school
Just keep reminding yourself that you're setting a GOOD example to your kids by displaying good study habits. If they see mom working hard on school, they'll be more inclined to be better students themselves. My son & I have a "contest" for A's (he's 13) and it's been fun studying together.
Best of luck to you!
