A good place to start, but not good for those with experience - Tutor bei GoStudent: Mitarbeiterbewertung

Pay. The pay might be good if you're an A level student/ early undergraduate. But if you've got a lot of experience, yet don't take on that many hours you can't get above the base rate of £13, unless you remain with one student for a very long time in which case you get bonuses. Due to the nature of teaching (students take breaks/only have tutors for exams etc) this means your pay effectively reduces if you start with new students despite being a loyal employee. There are bonuses available - such as £250 if you complete 150 hours in 6 months but obviously if you fall just short of that of course you don't get it and you're kept at the base rate of £13.
