He was abducted by Hagrid when he turned 11 so that would place him maybe around the fifth or sixth grade.
I don’t know if canonically there are math classes at Hogwarts.
The thought came to while I was watching the anime Mashle. If you are into Harry Potter and One-Punch Man I’d recommend giving it a watch.
Someone mentioned this community below; I wanted to highlight it.

Remember when Hagrid assigned his dragon the wrong gender at hatching?
Had to jog my memory, because I haven’t read these books in nearly 20 years.
But yeah. I think the Rowling of the mid-90s was relatively chill and fairly progressive, given the tone of her writing. It wasn’t until she got Disney-fied (or, I guess, Warner Brothers’d) that she took a turn. The novels really take a dive in book 5 and her political opinions just get nastier and nastier after that.
The Norberta reveal actually happens in Deathly Hallows. And frankly, I don‘t see a shift that is connected to the movies. What I actually observed was the overcompensation for criticism two books after the fact (remember Winky?) that Shaun described in his video essay.
