There are two levels of syllabus. The overall study plan is free to anyone and can be found here, under the Highlights section:
http://www.manhattangmat.com/freegmatlearningforum.cfmIt's called "Official Manhattan GMAT Course Syllabus." If you're not in one of our courses, go download this and see whether you think it would work for you (note: it includes assignments for
everything, so you may not have purchased all of the resources it references).
There are also two Excel spreadsheets that are available to students taking the course: one with very detailed assignments based on the overall syllabus (above), and another that allows you to keep track of your work within the Official Guide books.
