Apostrophe Usage with Numbers and Abbreviations

When it comes to referring to a group of CDs or DVDs, what is the correct apostrophe usage? I was taught, while doing freelance proofing of novels, that one should omit the apostrophe, that CD's is incorrect. I assume it would be "CD's" if you were referring to a characteristic of the CD, such as, "The CD's cover was scratched".

Similarly, when referring to pupils in grades.
"Grade 2s and 3s could do this themselves". Apostrophe or no apostrophe? Again I assume that a group of them would not have the apostrophe and referring to a characteristic of the group would have it: "The Grade 2s school play was incredibly boring".

Any clarity would be great.

There isn't much clarity. Many grammarians accept an apostrophe when the plural s is added to something other than a word and consider both of these correct: many CDs / CD's They are MPs / MP's. Others say that only CDs and MPs are correct.

  • I would definitely write: He doesn't dot his i's.
