They are in the 9th grade. This is proved in the orginal dub, the french dub, when Alya states that they are in their troisième-year ( 9th grade in french) in The Pharaoh.

Secondary education in France works a little differently, "College" is a term used to describe a middle school, or more specifically, a junior high school. It consists of 4 grades starting from 6th(ages 11-12) grade, ending at 9th grade (14-15).

In the english dub, when they said grade 10, they were going by the UK educational system which is the equivalent of grade 9 in the US and in France.
