I cried on my way home because I have just been waiting for so long to do it . We had to do these physical tests in order to get certified and I failed the 200 yard swim . ~_~ I was almost there , but it was the first time I 'd gone swimming since ' 06 and I got water up my nose and had been rushing . FAIL .

Question: What may be the cause of my sadness ?
Answer: None of the above choices .I put a plug on my nose but I still swam too slow .I have to try again for the certification .Swimming a lot lately did n't hlep me pass the test .
