For real? 9 AP classes and 10 AP tests is considered a low number of APs?
Generally, they compare that to the number offered by the school rather than compare the number this student took versus the number another person at another school took.
And I wouldn’t worry about the counselor recommendation - I’m sure those are mostly just facts like the school profile information, a comment on your attendance/behavior record, how many APs the school offers vs how many you took, your grades, etc., and not a commentary on your work ethic, enthusiasm for your educational experiences, your activities… those are for your teacher recs.
