Hi! First, check this out:
https://www.manhattanprep.com/gmat/blog ... our-score/That lays out the steps for you to take in developing your own customized study plan. Feel free to check any aspect of your study plan with us—we'll tell you where we agree or disagree with whatever you plan to do.
Couple of things:
—Do study a little almost every day...but also give yourself 1 day a week completely off. Don't even think about the GMAT that day! Your brain needs the break.
—If you are also working on weekdays, then you may not always have the mental bandwidth to do 3 hours. Expect that some days you might only do 1 or 2 hours. That's okay. You might even need to split it up some days (half an hour over lunch, another half an hour at a coffee shop before you head home, then an hour after dinner). In fact, breaking up your studies in this way can allow you to learn more!
—On weekends, don't study 9 hours in one single day. (I'm not sure whether you meant you have 9 hours over the two days or each day.) Your brain can only make and process so many new memories in a day (and it continues to process those memories all through that day and while you're sleeping that night). If you overload it, you risk wasting your study time by making low-quality memories (otherwise known as: forgetting things).
—Don't study for more than 2 hours at one sitting. If you want to study more that day, take a break (my rule is that my break has to be at least 2 hours). For example, have breakfast, do 2 hours, have lunch and run an errand, then do another 2 hours. I wouldn't do more than three 2-hour study periods in one day (and I wouldn't do that very often).
Okay, so go check out that article, come up with a study plan, and let us know what it is (if you like). Good luck!
