The teachers are generally good, but the lessons, especially the spanish 3 and 4 lessons, are just awful. For the most part I use third party sites to learn grammar, not to mention the lesson are 7-11 slides but only 2 to 3 of the slides are even relevant, which is the case for most flvs classes I have taken. I use flvs because the other online education sites are somehow even worse, not because I want to.
