good book collection you have
I'm just starting with nearly the same materials as you. I have a slightly different approach than the one, offered by the other people. It all depends on the you view.
As you think to dedicate the entire year to your preparation (I would rather change that and try to do until the 6th of June one attempt, as then the GMAT format will change and there will be new MGMAT, Kaplan
and OG books as well), I would start with both Foundation book, no matter in what sequence, and then make a GMATPrep CAT in order to gauge my level. Should be dobe in around 3-4 weeks.
Than have a look on the Kaplan Premier
to get some general feeling about the strategies, used in exam preparation and the GMAT itself.
Finally, start reading all 8 MGMAT Strategy Guides, whereas I think they are the most important source of information. Study them slowly, write down everything you don't know cold, and complete OG's questions mentioned in every chapter. If you succeed doing this in 2-2,5 months, then the remaining time until June can be dedicated to completing the remaining MGMAT CAT's as well as GMAT Prep tests.The error log is obligatory!
At least that's the approach which I aim to apply.
Thank you very much for reading this post till the end! Kudos?
