Well, the big question is, will you be a classgoer or a homeschooler? That will change your week drastically. If you're a homeschooler, then the only classes you HAVE to go to are Gross, PCM, and IMPS. Gross is always right after lunch MWF, PCM is always Tuesday or Thursday afternoon from 1:30-4:30, and you can never guess with IMPS, but we only had one IMPS meeting first semester. If you homeschool, then you will probably spend about 8 hours a day at home studying/listening to lectures (definitely can be more or less, depending on your goals and talent for memorization).
If you're a classgoer, MWF, Biochem usually starts at 8am (though it's 10 every once in awhile), and then you're in class until 2 on days you don't have Gross lab and about 5 on days you do have it (you alternate lab every other MWF). TTh, class usually starts at 8, and then you have class until 12 if you don't have PCM that day or 4:30 if you do (at the beginning of the year, your mod will be divided into 1/2 Tuesday and 1/2 Thursday PCM). I don't really know how much time classgoers spend studying. My guess is around 5-6 hours/day, but I know that depends drastically on how much the person gets out of lectures.
Remember that your schedule is literally different every single day, so these are just rough guidelines. Some weeks are worse than others. Hope that helps!
