DO YOU HAVE "PUNCTUAL" CLASSES?
This one is interesting because it is something that is often said by Spanish people. The classic sentence would be something like this: "I would like to have "punctual" classes"
If a native person hears this sentence they probably will think that the student want the teacher to arrive "on time" (not late).
The Spanish person, of course, does not want to say this. What they are trying to say is that they would like to have classes from "time to time" or sporadically when it suits them best.
Are you a punctual person? The English are famous for being punctual although that is not always true.
Hope that helps!
