Hi all, I scored a 680 (Q39 V42) on the GMAT recently. I am trying to do a retest in the next 30 days and looking for some structure and support. I'm considering getting an Economist GMAT subscription because I like the structure, but I've also considered
GMAT Club tests + Math Revolution. Since I'm weaker in Math I wasn't sure if the second option was the best for me, but then I saw something on this forum about the Economist GMAT CATS - Verbal is harder but Quant is easier

. I don't want to lose my V42 while I study to improve my Quant! My target score is 730 and I am looking to apply this September in R1 for Fall 2019 admission.
1) How long have you been studying? Four Months - Feb, Mar, Apr, and May 2018. I did a
Manhattan Prep in-class program for 9 weeks and then did self-study for the next 12 weeks or so. During the MPrep class I hadn't figured out a viable work/study schedule, so I only did the interacts for Feb and March. In April, I got up two hours early in the morning to study and then forced myself to leave work in the early evening so I could study for another hour before bed. In April I completed all of the MPrep lessons, and in May I completed the entire OG18 book.
2) When are you planning to take the GMAT? - Next 30 days or so. July 2-July 17 timeframe.
3) Did these CATs include the Essay and IR sections? And if so, then did you take those sections? Yes
MPREP 1 - Feb 1 - 620 Q38 V36 (taken before class started as a diagnostic)
MPREP 2 - Mar 1 - 630 Q39 V37
MPREP 3 - Apr 1 - 600 Q39 V34
MPREP 4 - Apr 22 - 640 Q38 V38
MBA.com 1 - May 13 - 710 Q46 V41
MPREP 5 - May 20 - 660 Q42 V38
MBA.com 2 - May 25 - 700 Q46 V40
MPREP 6 - May 28 - 660 Q40 V40
Official Exam - June 1 - 680 Q39 V42
4) Have you used any other resources besides the book and the practice problems that you mentioned? MPrep books and OG18. I bought the LSAT Supertest 1 to improve verbal in late May, which I feel helped. I still have multiple sections of that left.
I also have five Paper GMAT tests which I used to work on timing - my OG questions I always kept a timer on, but I kept working until I could complete the problem and then checked the answer and reviewed right away afterward. I would "soft bail" between 2-3 mins, look away, make a final guess, but then continue to solve and record another answer if I was indeed able to work out the question.
I kept an
error log, but in retrospect, I didn't review it enough. I had a tutor (briefly) who encouraged me to see lots of problems vs. study the same problems over and over. I feel like seeing lots of new problems was useful, but I never revisited my wrong answers except right after I got them wrong and reviewed at that point.
I reviewed

https://gmatclub.com/forum/the-error-log-129501.html, but I think my Quant just sucks in general, and I couldn't find anything about keeping verbal up. I'm also nervous that I've used up 6/6 MPrep tests, which are supposedly the best ones, and I'm pissed at MBA.com because those were giving me a more optimistic view of my Quant scores.
Hope this was all of the information you needed! Thanks in advance for the help.
