My senior year classes were pretty difficult; physiology, anatomy, pharmacology, etc. etc. I would say the classes are probably equally difficult, maybe a little more so, but it's a lot different being in pharmacy school vs. working toward a Bachelor's and comparing classes. First, depending on the school, you'll have a lot going out outside classes, or special labs/projects within classes that will make you time manage if you aren't already good at it. Second, when you're in pharmacy school there's a feeling of working toward something that you can grasp, it makes it a lot more satisfying to study harder and work harder now that you have a good picture in mind. Don't worry so much about how hard it's going to be, you'll find out soon enough and you'll make changes and adjust the way we all have. We all did it! Enjoy
