Can anybody post what their typical schedule is on a school day? I'm trying to figure out how much time will be left over.
Although this doesn't give an outline of my day, I can tell you that you WILL have free time if you are a smart and efficient studier. I never cram for my classes; instead, I study a little bit every single day for each of my classes. By the time tests roll around, I have my notes literally memorized. This greatly cuts down on my stress level, and I know that I am always prepared. You will have some semesters that are more time-consuming than others (my worst was when I had orgo and genetics at the same time), but even then, I still had free time. It took lots of work ethic, though, as I often spent 2-3 hours on orgo every day during the school week. When you have gaps between your classes, make sure you utilize them to study. I commute to school and find that I am often done with all of my studying/homework by the time I leave for home at the end of the day, which is usually around 1-5 (it depends on if I have labs or not). Be forewarned that you'll be in class a lot more than your non-science friends because of labs (they're often 3-4 hours long but only count for 1 credit hour for your GPA). You'll also probably have to do more studying than most of them, unless they're pre-engineering or something like that. 🙂
It's all very doable, though. Like I said, I have free time, and I don't put in much time studying on the weekends. You just have to NOT procrastinate and be a good studier! 🙂 My lowest final grade in any class at my college has been a 96, if that tells you anything. If I can have free time even while pulling 98s-100s on all of my exams, anyone can! 😀
