These were my latest mocks. Today I scored 530 (Q29 V34) after studying for 7 months. Shockingly, my IR was a perfect 8. I never studied IR and always tried the first few and guessed the rest during my mocks, ending up with a 1-3.

I have gone through all the MGMAT books, and lately have been relying heavily on GMAT Pill. I always review my mocks, whether I get the question right or wrong. I have no idea what happened to my quant. During the exam I felt like I was nailing the ones I knew I would get correct and only guessed on a few difficult ones. On verbal, I believe RC really threw me off. The passages were dull and the questions seemed more difficult than I was use to.

My goal is to get between 640-660. I know it's possible, but I don't know where to go from here. Continue using GMAT Pill, open up the MGMAT books again, or look elsewhere? I have a little over 2 months until apps are due. I can squeeze in 2 more real tests, but I think I should focus on taking it just one more time and hoping for the best.

A couple notes:
- I went out of town this weekend with my girlfriend and friends, so that could have thrown me off. I didn't study when I got back either, just reviewed a little bit.
- This was the first time I took the test with AWA and IR. I started only taking the Q/V, then only lately added the IR. And like I said, I would just attempt the first few problems of IR and guess the rest. I never attempted a AWA, but I didn't have a problem answering it during the test. However, some mental fatigue may have set in.
- The exam location was a little less than 40 miles away from me. With traffic it took over an hour. The next one I register for will be about 10 miles away/15 minutes away.

I don't like to make excuses, but those could played a role as to why I did so poorly.
