Severn is trying to be a top academic school that will hopefully separate them from the lower academic schools like St M and Spaulding. The list is on line. Gilman was #1 followed by Bryn Mar( one of Gilman sister schools) Hilton Arm ( a girls school in Bethesda then some other Montgomery county private schools I haven’t heard of the G’town prep and McD was close to them. BL was the next MIAA school somewhere further down on the list followed by St P then Loyola and way down CH. There are multiple list out there that rank by different criteria but the pecking order is basically the same.
