I admit to being confused with your story.
Why would you spend 30 minutes of test time cramming keywords— as opposed to taking the test??? IF you were ill, you should have been hurrying to get the test in-- or asking THEN if you could leave. Not cramming keywords so that you could have an advantage, or give someone else an advantage, at some later date.
You “had a tooth ache and (were) uncomfortable”-- and for that you left an exam??? Because of discomfort? Or was it a cold that required a tissue? As opposed to, say, taking an Aleve, getting through the exam, and getting to the dentist?
You should have known exactly about the test when you took it as every other student taking that test. You were trying to game the system-- we call that “cheating” – and you lost.
What are you hoping to get out of this thread? Advice? Sympathy?
