The teacher I have and the customer support are extremely professional. The prices are a little higher per class but for the quality it is well worth it. The teacher is very orginized, remembers what I need to work on and what I do well with, it shows that they spend time reviewing the classes after. They send regular reports on progress and are not shy to call you out when you haven't been practicing. They are flexible with scheduling and extremely responsive to qeustions outside of class. I thought 1 class a week would be good pacing but quickly realized 2 a week would be best. The teacher introduces only a few new vocabulary words each week but builds on them week to week. Homework is difficult and the teacher requires me to translate audio sentances without any hints very early on which has helped my listening a lot.
