The pricing model needs work. You probably want to be selling minutes in blocks and offer volume discounts. 60$ an hour is kind of high for online tutoring as well esp if quality of tutors is quite variable
Re: the $60/hour rate: given that online tutoring prices can vary pretty widely (anywhere from $10/hour to $200+/hr), I actually think it's fairly reasonable for a high-quality product. My hope is that the quality of tutors won't feel too variable in practice even if students end up working with different tutors for every session -- it's very important to me that we keep a high bar for all tutors on the platform, so a lot of work goes into the vetting process.
I used to tutor LSAT; 60 USD per hour was highish, but not that crazy in 2017/2018.
