Thanks for the cooperative responses from everyone. I don't have time to write full replies to all of them (or I'll find myself spending too much time on VN), but I've taken all your replies into consideration. At the very least, I think I'm willing to give it a shot; I'm going to discuss with some other friends first, but I think it's very likely I'll be applying within the next day.
As I understand, after the first two lessons, I can choose to discontinue and receive a refund? I would just like to say in advance, if I find the lessons to be ineffective, I can't afford to keep going with it just for the sake of courtesy. I'm taking this (both my own responsibilities and you as tutors) seriously; if it proves inefficient, then I'll do what must be done. I'll be treating you guys like professionals, which is an indicative of my respect. In that event, no hard feelings. Of course, we don't know what will happen yet (after reading this you may feel that I'm skeptical of your abilities. That is not the case, or else I wouldn't bother enrolling), so this is really just a precaution I felt I had to voice. I hope you guys understand.
With that aside, I'm looking forward to meeting everyone. Hopefully I'll be seeing all of you soon.
