Good tips!

Here are a few of my own:

The student disability office at my university runs all kinds of free workshops that teach study, stress management and life skills. If your school offers such workshops, sign up.

There are often upper level students taking first year courses. Befriend a few. Their guidance and friendship is invaluable in navigating the first year experience.

Be realistic with your abilities and situation. I had to drop a class because I felt very overwhelmed.

If you have a problem with a class reach out. Don't wait, until the last minute. Most professors and TAs want to help and see you succeed.
