Mind what you have learned. Save you, it can! ~Master Yoda
Check the syllabus! It will list what's planned for class every day, test dates, project due dates, etc. What a handy tool! You're welcome.
Keeping track of things is like driving this bus up a narrow road. You've got to be VERY aware of what's around you, and make course corrections in a timely way. But, this bus made it up the hill, and you can, too.
