Foster school chances

Hello, I am an international student who is studying high school completion and AA in WA. I am aiming for UW Foster for this fall, majoring in accounting. Here are my stats:
CGPA: 4.0
bus major pre-reqs (completed) GPA: 4.0
(Pre-reqs that haven’t complete: Managerial accounting, business calculus, business law)
Activities: PTK chapter vice presidents, some volunteer, some business related events back home, tutoring job (won’t start until April- did not put into my application)

Questions:

  1. Does that make me a competent applicant? Let me know if you need more info for your judgement.
  2. How hard is WSA? How does that relate to TOEFL (I got a 27 which is not really competitive). I am going to take WSA in Feb, any recommendations on studying?

Thank you very much and I appreciate your time and effort in answering!!!
