Confused?
Get help from Grove and Evans AM or PM!
Did you know that the amazing, stupendous, and punctual Mr. Jeremy Grove is available Tuesday and Thursday mornings before school to field your math questions? Stop by between 7:30 and 8:00 for help! 6th 7th and 8th graders are all welcome.
And for those who love their snooze button just a little more than math (honestly, I can't blame you) then stop by room 7 on Tuesday and Thursday before 4:00 for help from Mr. Evans. Come one come all.
Also, stay tuned for information about an official River School afternoon tutoring program.
