Great Course (760 49Q / 46V 8 AWA 6.0 IR)

Manhattan provided a great deal of value. I was able to score a 760 on my first attempt at the exam. Abby Berry was an excellent teacher and the timelines are laid out well. In addition to the classwork, you get access to the online interact sessions, which provide a second chance to review items where you need extra help. The books are well laid out and provide a lot of practice. GMAT Navigator is an excellent tool to track your progress against the official guide. I only took the test once, but I think they give you access to the materials for 18 months from when you sign up, which seems very fair. Customer support response time is excellent. I wanted access to their advanced quant book and sent an email on a Sunday afternoon. I received a response within an hour.
