what to do if i take 2 weeks off of studying

Hi, i have midterms spread apart for the next two weeks and I don't want to really focus all of my effort, like i've been doing recently, towards the GMAT. So i'd like to take some time off, probably around 2 weeks so I can finish some of the midterm work. I am using the 60 day study guide and I just started day 13 and did O.K. on the math topics so far, but am worried that If i take these 2 weeks off and jump back into the math I might get rusty on what I learned so far. Do you think that will be the case? Do you suggest I do some light gmat work during the time? Do you think I should just not worry and try to keep up with the 60-day study guide & midterms? Any advice on what to do and suggestions on how to keep from staying rusty would be appreciated!
