Right now I have class on Monday, Wednesday, Friday from 9:20-10:10am, 10:30-11:30am, then from 12:30-1:30. I have an hour to get across campus, eat lunch, and get prepared for my third class of the day. On Tuesdays I have an 8:50-9:40am Italian lab and class from 12:40pm-2:20pm (again an awkward break from around 10-12:40pm when I usually am tempted to take a nap). Thursdays I have class only from 12:40pm-2:10pm. But within these classes I have oral exams for Italian, special speakers I must attend for participation, online homework, and outside of the class due dates and professor meetings. This throws me for a whirl quite often and my week to week schedule is never the same.
I recommend PLANNING AHEAD. Making yourself "study blocks" where you sit down and have an hour for each subject a day. I recommend getting your homework done in advance and planning your papers and research in advance as well as they most likely involve extensive research and different citing then what you are used to. Unfortunately it is not like high school anymore and papers can be 3 or 4 pages, or 12 at the most for a semester long research paper. In college you will have 3-5 page papers due weekly, 8 pagers biweekly, and detailed research assignments. Go visit your professors with questions and don't get in the habit of procrastination. You will get overwhelmed and either harm your GPA or get sick. Neither of which is fun.
Cliffnotes for this post: Don't procrastinate on anything. If you are in this habit in high school...get out of it quick and start planning ahead and doing little bits of homework, paper research, and studying ahead of time. In the long-run it will help you.
