First off congrats on being in your last semester, I envy you! Have you already been dismissed from the nursing program? Have they formally told you anything in writing or sent an email dictating you to retake the test? As others said, retake the test immediately. Try to refrain from taking supplements, preworkouts, diet pills, and meds such as adderall as others stated till after the test. Best of luck, keep us updated and congrats on your last semester.
