Not in the scenario you've originally asked about, no.Is there any context in which 'It's going to be a (party, quiz, sports day, exam, etc) on Tuesday! ' could be right?
Not in the scenario you've originally asked about, no.
So basically there, "it" amounts to being something different from what "it" normally is.
Thank you so much, DonnyB and Chez. Now I understand the case much better!Just an additional note: a 'quiz' (in BE, anyway) has the connotation of something you do for fun ...
If you have to stay in to study for something happening at school, it is more likely to be a 'test' or 'exam'.
Thank you, Ponyprof!In North American English we do say quiz usually for a lower stakes shorter test that might be sprung on students with less notice, or none (a pop quiz).
An exam is a more formal higher stakes test typically at the end of term (final exam) or midterm.
Test is a general purpose word, it could refer to either of these.
