Don't forget - today is the add/drop deadline!
Sometimes, it's just not the right time to be taking all of the courses you are taking (or sometimes it's all working out perfectly and you don't need to make any schedule changes). If you fall in the first category, don't sweat it too much, dropping a course is not the end of the world, and it's not really that uncommon either. Sometimes it is the best option for your mental health and your grades in your other courses.
If you are considering dropping a course, you only have until the end of today - March 2. If you are concerned about how to get back on track if you do drop a course you can take
a spring or summer course
and you can
talk to an Academic Advisor
to consider other ideas as well. After March 2, it will be a lot harder to make this choice so don't leave it until later to determine what is right for you.
