What have you done to help yourself?
Have you been to your prof’s office hours for extra help?
Gone to the extra help office? There’s one on campus somewhere.
Asked about a peer tutor?
Formed study groups with your classmates?
Found the right online video to explain each topic? The first one isn’t always the right one (and I’m SO not a fan of Khan Academy-- if I were struggling I would keep looking.)
It sounds to me as though you “procrastinate and also do not study smart when it comes to tests.” So of course that’s where you’ll need to start.
Being stressed out isn’t the solution. Action is the solution.It’s time to act.
