WOW! Seeing that this is run by two former students with no education experience, $85 is an absurdly expensive price IMO, especially in these times.
What did Daniel receive for SLA? I see you have conveniently left his scores out 
Hi James,
Thanks for the reply. First, I have been tutoring students for the subject this whole year, and have been tutored by teachers who do charge much higher rates. Our aim is to help students from a past student's perspective, who has also learned from teachers. That is the value.
We believe $85 is a fair price, and it is what we are charging for supplying our services for the time of two people. The demand depends on the value students see in attending these sessions.
As for Daniel, he got raw 38 for SLA. Not sure if you understand, but SLA are native speakers, let alone being in top ~10%. That is 绰绰有余 for SL.
