Hi Rishovnits ,
Three months is a good enough time to improve your score. If you are willing to study dedicatedly for that period, you are sure to achieve your goal. I believe you may benefit from taking an additional course. If you are willing, there are some great GMAT prep companies that can help you with 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. Further I see you are a new member here at GMATCLUB and when you sign up at GMATCLUB you get a free 3 days access to EMPOWERgmat course. In fact it is the only way to get the deal which is very kool. They also have a great 3 month study plan which might be helpful to you. You can also try free access to
Magoosh and Optimus Prep so try those out as well.
Also I would highly encourage you to consider
e-gmat verbal online or the
e-gmat verbal live course. They are both amazing courses especially designed for non-natives. They offer almost 25% of their courses for free so you can try out their free trial to decide which one you want to go for. Plus the
e-gmat Scholaranium which is included in both the courses is one of the best verbal practice tools in the market.
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 a 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 to purchase the latest version of
OG and the verbal review for some great additional practice. Here is a link that will help you with your decision.
