They were unable to help me with the problem I submitted. After being passed around to about 3 tutors without any instruction, they refunded my money. I've written this review because I saw other reviews that said they didn't refund. In my case, they did. My rating of them is neutral. That they couldn't help me may not have been unreasonable. I've had many college math courses and I couldn't see the solution.
