Morphology
Though 'mind' means 'be careful', the phrase 'one's Ps and Qs' is an idiomatic reference (with unclear historical origins) to manners and behaviour rather than to the literal letters P and Q. A B1 learner who knows the individual words would not be able to derive the meaning 'be polite/behave carefully' from the constituents, so the expression is opaque.
Etymology
Mind one's Ps and Qs may come from old printing shops, where workers had to watch the small metal letters P and Q because they look similar and could be put the wrong way. So the phrase now means 'to be careful about how you behave and what you say'.
