I have a lot of national awards in one specific area that I can’t squeeze into the Activities or Honors section. Would it be a good idea to put them all in the Additional Info box? I’ve also heard about making a Zeemee profile but honestly I have no idea how that works. Thanks!
You can bullet them in the Additional Info section, no problem.
First, try to combine them if possible, for instance, same award from different years. If it does not work, then list the most important ones in the award section and let the less important ones overflow to the additional information section at the end. I would not leave the national ones in the additional information section as that may be overlooked.
