Whoops - realized I hadn't thanked you guys! Thanks so much =)
I knew I nailed argument but honestly, on issue, I felt like my examples were weak and I was trying not to exert so much energy on it so the 6.0 was a surprise to me. I was also surprised on how fast they graded it - in 4 days?? Wow.
VP_Jim, you're right --- to all you liberal arts majors out there, remember that the GMAT quant is not fundamentally difficult. It's tricky, and that's what trips you up. But pretty much all this stuff? You learned it in high school! I *hate* math and obviously, I didn't ever expect that a 50 or 51 were within my grasp, and a 48 was more than good enough for me.
Relearning the math works for some people but honestly, if you're not a math person? Learn the shortcuts. Plug in the answers, plug in numbers for DS, POE anything that's way out of range, almost ALL GMAT questions can be solved this way. If the algebraic solutions come easily to you, go for it, but if not, don't waste time trying to relearn them -- 99% of the time there is a way to do it that requires way less variables and much more simple arithmetic (which, by the way, I had to review -- I had forgotten how to carryover in subtraction-by-hand!!).
Thanks again to everyone at BTG -- I couldn't have done it without you!
