Just be prepared to be bored out of your mind at times in basics. There are some subjects here that they just draw out WAY too long. We probably spent the better part of 3 hours on runway/taxiway markings and lighting, only for there to be not one question on the block test about them. If you went to a private pilot ground school, they could teach the same in about 30 minutes at most. While there are some subjects that really do take that long to teach them properly, there have been some that include (IMHO) a bunch of filler material to make it take up more time. Your individual study time will vary, I walked in here with an instrument rating, so everything so far, except for some of the general aspects of separation and radar, have been review for me. If you have similar experience, expect it to be much the same for you. If you do not, you will probably need to take some time nightly to at least review your notes and read through the binder they let you borrow, if for no other reason that they are throwing a ton of information at you rather quickly at times. The material is laid out in a way that you do not have to have any prior experience to be able to understand it, but as one of my fellow classmates mentioned, it is just quite a bit of material.
