Yes, like Spencer said, "hot and bothered" is an expression. The two words go together. It means that you're agitated or upset about something. For example, "She was all hot and bothered before her performance at the ballet."

Hot and bothered is an expression meaning worried or concerned :)

‘hot and bothered’ means agitated.

Hi Ken, Hot in this context mean that joseph was angry and annoyed that he had to get an A anyhow on the test. Hot here is not really the tempreture of on object but it's his state of mind, how he is feeling from inside. Hope this helps. Have a nice day!

A good definition is 'flustered' meaning, as Alex has said, 'agitated'. It usually refers to an immediate situation, rather than concern over a longer period of time.
