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.

Hermione mentioned in the first book that wizards tend to absolutely suck at things that are typically Muggle, like logic, so it follows that they probably suck at math too.
Logically, that does follow, but we’re talking about wizards here.
True, but their methods of learning do not differ significantly from that of muggles. They still need to take classes the same way we do, and this would need to learn maths and logic the same way too.
Whoosh?
That’s probably why wizards don’t run the bank 😂
