I removed the "rough guide" to US grade levels because it was inconsistent and not needed with the table. I also fixed the ages in the table and made first and second grade not be combined because the user who combined them did not provide a reason for doing so. I removed college professor from the table because I'm unsure what age that should correspond to, but if someone does know they can add it in there. |
