U seem pretty good for a 30 day prep! Kudos!
With just a week left, try to do the following:
1) Try to give more CATs. There are some free tests available from
MGMAT, KAPLAN etc. . They are never better indicators of your score than GMATPrep, but usual to time yourself and practice, also for knowing your problem areas. [and if you can manage 25 kudos then
GMATCLUB tests would be good option]
2)Try check what kind of questions are you finding tough or taking more time for and focus on them.
3)try solving at least 1 question each day on each topic, while focusing on the your weak areas more!
4)Try solving the hardest questions on GMAT club and dive dive through the explanations given on the forums.
5)RELAX- you are pretty on track with your preparation so dont start learning absolutely new areas!
All the best for your exam! Do post your debreif!
