Time Management: Key Calendar Dates
You need to know relevant dates from MIT's Academic Calendar. You can download it to your phone or computer, and set alerts for deadlines important to you. At the beginning of each term, be sure that you have Add Date, Drop Date, Pre-Registration, and the Final Exam week in your personal calendar, with reminders set ahead of each date.
On the first day of each month, October through April, check your Status of Registration on WebSIS to make sure it shows all classes you are taking—and none that you're not taking. This way you'll have plenty of time to make changes before Add and Drop Dates.
Pay attention to emails from your academic department, which often announce visiting speakers, internship and UROP opportunities, and departmental events, all of which have dates or deadlines.
