Hello uwevr1,
I kind of identified myself with you. I am stuck on the same place for a while. I did an official GMAT couple of months ago and got an embarrassing 400, then I thought: "Hey, I am reasonably good at Math, at Reading and all, so I am going to fully study this". So, I started using
MGMAT Guides, some random practice questions, question banks from Veritas Prep.
After 5-6 weeks, I did an entire Veritas Prep CAT and got a 560 (Q32 V35) and felt a little bit better with myself, but what bothered me was the percentile difference between Quant and Verbal. After that, I kept studying the same way and it took me 4-5 more weeks, but, sadly, got the same 560 (Q38 V29) on my second CAT. The difference from the second to the third, was a slight improvement on Quant, but a decrease on Verbal.
Since then, I have been studying using a Study Plan for Quant I found here (could not post the URL) and bought the OG 2015. Right now, I try to keep 1:30 to 2h of study per day, did the first 100 and start building an
Error Log. I haven't had any practice or online lessons on strategy yet, I want to make some improvements and get the all the concepts solidified.
I just want to say that self studying is hard, I feel that quantity study is not necessarily effective, I need to have some guidance because we are no benefiting from a pre-formatted course and frame.
I try to keep myself somewhat knowing I will the so desired 700!
Cheers!
