dont fall for those, theres are so many web sites and books that are like "learn the guitar and feel like those in 30 min" or "master the guitar in 7 days" and stuff like that... Basically to master the guitar, all you need to do is learn songs, but scales can help. If you want to learn something, find it on the internet and if that doesn't work, get a book about the particular thing you want to know, not a whole set about everything. And im almost positive the lessons are pretty bad.
