Prep101 gives EK books which is priceless.
I am not sure how it is, but ill be taking it myself this time so.
Also, I know everyone says that courses are useless which is probably true. But it is invaluable when it comes to keeping you on track. So if you know you have trouble keeping yourself on track, and you probably do because everyone does, then go for the course.
Even if you think you can self-study, which was my case because that is how I am in university, I don't go to classes because I can't learn from professors all that much. I would still recommend taking a course just for structure because it is extremely difficult to do that yourself.
Do that or find a buddy, and meet everyday, not to study together, but just to give each other the push to continue.
