Month 1 and 2 go through all of the MGMAT math guides, the MGMAT SC guide, the MGMAT CR . Make sure you're constantly reviewing the material you cover. Do not cover a chapter and never return to it. Constantly review the older material.
Month 3: Begin taking a practice CAT a week. By now you should have completed all of the books. This is what you need to do going forward with the math books. 2 days a week designate those as math days. Do two problems from every end of the chapter problem set from each chapter of each book of all of the Manhattan GMAT guides. For example. On one day you may do problems 1 and 2 from every single chapter in every single book. The next math day you may do problems 3 and 4 from every single chapter of every single book. The reason I think this is important is that it serves as an active flash cards. It will stop you from forgetting the material, so all the gains that you make you will retain. With verbal, do 20 SC, 20 CR and 4 RC passages each verbal day (twice a week)
Month 4: Do the same as Month 3 except begin to really focus and hone in on timing. Make sure you are confident that you have timing down, so that is not a concern on test day.
Good luck.
