Sorry to not have anything helpful to say; we don't seem to have math competition teams in our area (or at least I haven't been able to find any yet) so I am not sure. I did just Google Mathnasium and they are in our area but their main/regular (i.e., not math competition) stuff looks remedial-ish, unless I'm misunderstanding. I don't know about TriMathlon--are there other options in your area? Or online options? I am trying to learn but have struck out so far here (Research Triangle area, in NC) and was thinking maybe in middle school there might be more or online options.
Good luck with TriMathlon
