If Ponyville has only one school, like a frontier town such as Walnut Grove in Little House on the Prairie, then the ponies seen in the classroom could in fact be a wide range of ages. This could also explain why many have cutie marks and many do not. I don't recall seeing more than one school in the series, and most younger ponies are simply described as "school aged", so this seems quite plausible.
