Hi Nathan! Glad to see you've started training. If the exam you took was a ARTCC issued exam, you must contact them to re-assign the exam. They may have a waiting period (look in the SOP's). If it was an exam (S1,S2,S3,C1) administered by VATUSA, the mandatory waiting period is 7 days. If the test was assigned by VATUSA, the exam will automatically be re-assigned after the 7 day waiting period. Good luck next time!
