Hi tali-p,
I would take the Manhattan GMAT virtual online course. Virtual means that there are live instructors teaching the course, it is not a recording. The classes are very interactive and engaging, too. If you need a well designed, structured study plan, I would definitely take that course. If you do all of the work that they assign you, I am sure that you won't be disappointed. Manhattan GMAT is the best test prep company around.
By the way, I believe that the Manhattan GMAT online course is available to anyone who has a PC and an internet connection.
