FirstTutors have a decent amount of maths and physics tutors, mostly on the budget side. I imagine this is because many seem to be new tutors who do not have much reviewer reputation yet. This is a good place for a bargain if you are willing to take a risk - I got a cheap, new tutor who is doing a fab job. If a tutor has a bad review, it is counted but not displayed - rather irresponsible if you ask me. I came out a winner this time, with a great tutor, but I wouldn't be surprised if many parents come away disappointed. FT has a largely passive model - they don't seem to do much in actively vetting tutors, no DBS is required to be listed even. They do not help punters find a match either, with limited, web-based search facilities and no personal interaction. FT seem to earn their fee for not much effort from their end. The fee structure (2017) is also a bit annoying - £20 for one tutor or £25 for multiple tutors. Most people will only need one but he/she turns out naff you would have to stump out another £20 for a replacement. In conclusion I'd say it is a good site for a tutor if you are on a budget and willing to take a little gamble. It worked for me.
