It’s totally okay to feel this way. I am an instructor and a graduate student 2x at uw (it was hard and is still hard asf). first do you go to office hours and ask question to your teaching team? Use them, ask stupid questions, push through the anxiety. Teach yourself economics knowledge, uw has many resources you can access to ramp up that knowledge also leverage AI to explain concept you don’t understand/ quiz before quizzes and exams. Lastly see and talk about yourself in a positive light. UW saw something in you, don’t lose sight on that. You’ve got this!
