I just wanted to say thanks for the help that GMAT Club provided in my journey to get to 700 yesterday. I know this is not the best score but something I can definitely live with. I have been studying on and off for the last year. I took the test last March with barely any studying and got a 630. I took it again in September after a lot of studying and using Knewton and got a 650, with a Q39 V41. After the 650, I bought the MGMAT books
and reviewed all the math study guides in order to learn the basics. I have always been absolutely horrible at math and pretty good at verbal so I did no verbal study whatsoever. I worked through these guides and learned a lot but I must also give a lot of credit to the math book and flashcards here on GMAT Club. I took every topic and every formula and wrote them down on flash cards that I would study at work, at other people's houses, etc... I seriously think learning all these formulas is what helped me drastically improve my score. I got many questions yesterday, like an overlapping set with 3 different groups question, that because I knew all the formula's from the GMAT Club math book, the problems were very easy. My final score was 700 Q44 V41, my math score was 66% but I am pretty confident that this is the best I can do. I put in hundreds of hours of math practice and never really broke Q44 even in practice. Thanks again guys!
