During the first week of school, professors pass out the 10-20-page manuscript of course content. This syllabus becomes the bible for students. Your syllabus is filled with vital information on grade cuts, test and paper dates, and teacher policies. If you want a good grade, do what the teacher explicitly outlines that in the syllabus The professor goes over the syllabus one time to make sure everyone is on the same page, and from there it's every man for himself. The syllabus tells you when your quizzes are and when your papers are due. Syllabus week means little instruction in class, but you're still getting vital information to ensure your success in the class.
Your syllabus will have the dates for every single test, paper, and homework in it so write them down in your planner or calendar app on your phone/computer/tablet. If you plan ahead, you can budget your time wisely. This leaves more time for the stuff you actually want to do, such as getting involved with organizations on and off campus, going to the gym, etc. You can alleviate stress by not procrastinating, being aware of your test dates and assignment due dates, and having one dependable friend in each class. Once, I did not read the syllabus for a course and showed up to my midterm unprepared because I did not write down the date in my planner. I have learned from my mistakes and now read the syllabus.
Syllabus week gives you a chance to know what you're getting yourself into, and it is a perfect time to party. Before you get assignment after assignment, take some time to have fun with your peers. Buy your planner, rent/buy books (if needed), and get on your teacher's good side by making a good first impression.
