Those are GA.
Just my take, the Berm is great if you're going to be back and forth to the playground. Doubt a 2 and 4 YO are going to be running around too much. However, PLEASE be very mindful of the game and sharply hit foul balls, they have installed some netting protection of the berm but if your closer to the playground is worthless and people get hit every year.
GA is both grass berms, and 202-204.
Students primarily sit in 202 (old 203), visitors in 201, and older GA in 203/204.
The rest of Olsen is "reserved" seating.
