I need to find a tutor, maybe more than one, to help my boys catch up in some subjects. It seems as though their previous school let some things slide. Hopefully this will be for a few sessions only.
My question is, from those of you with experience, is it better to go by recommendation or would I be okay contacting one of the myriad of agencies that advertise online. We've never used tutors before so this is a completly new venture for us.
TIA
