Student Profile: Dawid Szatan

Although Dawid Szatan is not in the exact range, he is only 2 years older than the limit. The school says "most" of the students are in the 9 to 15 range making it possible for Dawid to be in the school, making it possible for him to be an anomaly from most. There maybe the possibility of a late birthday which we are unaware of because we are only given with his birth year, drawing him even closer to the desired birth year range.

Did you also consider Dawid Icchok Szaten, born in 1929? He looks like he might be a slightly better fit.
