This is unsurprising if he did Alg 2 in middle school, for example.
What math did he take during the main Covid virtual year (2020-2021?) Algebra 1? That year MCPS officially cancelled a big chunk of Algebra content and waived end of year testing. So if you didn't supplement at home, you had a time bomb lurking through Geometry, and Algebra 2 might have seemed easy because the teachers were showing short-sighted post-Covid grace.
This is why I had my kid retake Algebra 1 in 8th grade.
Seems this is a common problem now for kids that were over-accelerated and then missed a lot of Algebra content.
