I’ve worked with Right for about 2 years and they really stand out from the other tutor agencies that I’ve worked for.
They provide you with all the resources that you need to tutor in your lessons and they provide a lot relevant materials and a point of contact for any questions/help that you might in terms of tutoring.
You can organise flexible lessons as well, so if you’re studying and/or if you have another job then there’s no conflict in arranging lessons at a suitable time for you
Cons
No cons, really haven’t had any negative experiences
