Maths tuition and swimming now clash at 6 pm, two evenings a week

All summer her tuition was at 11 am. Now it's 6 to 7, three days a week, and swimming is 6 to 7 on two of those days. She wants to keep both. The tutor has no other batch. Do I look for a new tutor in the middle of June, or push swimming to weekends?
