ou don't have anyone to take your questions out, you can't ask for help in an exercise or something like this, if you don't understand something in your book you can ask for someone to explain better, if you're not disciplined and organized, you can distract a lot and do other things unless studying, like Tv, snack, Computer, games, and you can procrastinate a lot, you don't have a timetable, usually you don't know where to start, but all these things you can change with EnglishExperts, that helps a lot in a self-teaching.
