I am currently writing my first CV to apply for grad school. While doing so, I am confused about how to write about some competitions. I tried to find this on internet, but the answer seemed not really uniform. I am particularly looking for the usual case in US, and field of applied math / CS.
Say a competition awards '1st prize' for one person, '2nd prize' for 3 people (2-4) and I got "3rd prize" with 8th rank in performance (awarded to 5-9). In this case, am I supposed to write '3rd prize' or '8th place (3rd prize)' or something else? It would have been easier if the award itself had some distinct name (such as bronze medal) but it officially does not. In these cases, what will be the usual way to write about this?
