Since "400 level" should be hyphenated as "400-level", should "300 or 400 level" be hyphenated as "300- or 400-level," or is there another way to write this?

    What comes after it? 400 level is not necessarily hyphenated at all....40-year-old man but: he was 40 years old.

  • @Lambie: it's in reference to courses (i.e., "a 400-level course") so it seems necessary. Feb 28 '19 at 23:43

    Yes, "a 400-level course", same for all the other levels, too.

"300- or 400-level" is correct. However, if you have "to" in between, I would write it as "300-to-400 level" or "300-to-400-level".

  • Indeed; that's why I edited the original version (I meant to write 'or' and not 'to'). Feb 28 '19 at 23:39

    I think you removed one "to" but not the other. It's still in "300 to 400 level." That's why I wasn't sure whether you meant to use "or" or "to."
