I have recently got a tutor to support my dd in maths. She is a current primary teacher (in her 20s) but seems to tutor for at least 3 hours every night. (We asked to change day but she isn't free until nearly 8pm other nights). How does she manage this? Would her class suffer or just her social life? How common is this? It seems an awful lot on top of a full time stressful job.
