We also let people attend a first class for free (limited slots available, though), so if you want to get a sense for the curriculum and teaching style, sign up for one of those (look for available dates / times on the 9-session classes part of out web site).

If you do the Guided Self Study Prep Plus, you will get access to all 9 class recordings. Just be aware that (of course) you won't have a live teacher, so you won't be able to ask the teacher questions during class. For that, you'd go onto the ManhattanGMAT forum; you can still have questions answered by teachers (including me!) but you may have to wait a few days for a reply.

The Prep Plus also gives you two half-hour private tutoring sessions via phone, so you can ask some questions there, but you'd want to save your biggest, most pressing issues for the private tutoring, obviously. Use the forum for posting test or OG questions and asking about very specific issues.
