Hoping someone with CBA experience can help a little - I'm looking for a bit more info on how the groups are organised e.g. numbers of students per group and typical age / ability level by group name eg Junior Girls 1 or 2 , Mid 1 or 2 girls - what level (or grades?) / ages would typically be in those groups? Also, Is 1 or 2 a higher group? I'm guessing Prep 1 is the 8 year olds and seniors is the 16 year olds but other than that I'm pretty clueless πand would appreciate any insights! Thanks so much
