What’s important is mastery and confidence at every level. For everything except pure math, math is a tool. Economics, physics, sociology… it helps when you’re explaining concepts or data with numbers to feel like it’s a language you speak. Fluently. Maybe even cleverly.
I would suggest dropping back a level on what seems to be a speedway of a program. For a kid with some ability, which your kid must have shown to be placed on this track, this should not be a struggle. Challenge is fine, but for something like math, which is sequential, your kid should ultimately win the match. Convincingly.
