Hi Kalian,
Two months should be good enough to improve your score. You should take a GMATPREP test and see how you perform. You can know your weaknesses and work on them. If you are willing to study dedicatedly for Three months, you are sure to achieve your goal. I believe you may benefit from taking a GMATPREP course. If you are willing, there are some great GMAT prep companies that can help you with your preparation. Although
MGMAT is good, you should also look at other online companies for your preparation.
In order to make an informed decision I would highly encourage you to go to their websites and try on their free trial and decide for yourself which one do you like better. You try out free access to EmpowerGMAT,
Magoosh and Optimus Prep as they have great reviews on GMATCLUB.
You can also try out the
MGMAT guides they are phenomenal and cover the entire syllabus really well. I must add that if you are particularly looking to discover and improve on your weak areas in quant; a subscription to
GMATCLUB tests is the best way to do that. They are indeed phenomenal and will not only pinpoint your weak areas but also help you improve on them.
Further taking multiple mocks might help. Apart from the GMATPREP,
Manhattan GMAT tests and Veritas Prep Tests in my experience have good verbal and Quant section and will certainly help you point out and improve your weak areas.
Further another advantage of taking many mocks is to build up your stamina. Apart from the GMATPREP tests, taking practise tests of any major GMATPREP company ought to do that.
Lastly I would also encourage you practice all the questions twice from the latest version of OG and the verbal review. Here is a link that will help you with your decision.
