So had a pretty horrendous GMAT exam today. Got a 630 after GMAT Prep CATS at 710 and 730 respectively. A number of things went quite wrong, and I think folks here may be able to learn from my mistakes.
1. Don't study the night before. I was. You don't get enough mental rest. You have to convince yourself that last minute studying will not help no matter what. Even if it does, the focus toll it'll take on test day is probably not worth it.
2. Sleep well and stick to your schedule consistently in accordance to your test. I had a habit of sleeping at 1 everyday and decided that i'll just sleep early the day before for a 9 AM test. Got into bed at 11, was awake till 1, and woke up at 5:45 instead of 6:45 (I have trouble sleeping at nights anyway). Anyway, I didn't get enough sleep. Get into a system and stick to it. You need those 8 hours.
3. Calm down and NAIL those first few questions on the Quant and Verbal. Your accuracy on the first few questions is CRUCIAL. My mind was off on Quant during the first 5-6. I believe I screwed up the start. I then proceeded to get consistent and felt I was only slightly under-performing my usual self. Saw too many easier questions. Knew something was wrong. Your performance on the first few questions shall set the exam up for difficulty and it will be very difficult to dig yourself out of the hole if you mess up early. Q42 when I'm more accustomed to Q47-49. Started off Verbal with a bang and lost mental stamina towards the end. V34. I might have gotten some of the last few wrong. The algorithm will F you up if you falter at the end as well. At least that's what I felt.
4. Don't drink too much water before the test. I seriously don't understand what happened but I had to take toilet breaks during BOTH the 8 minute breaks, and more importantly DURING both, my Quant and Verbal sections. I have no idea what the heck was wrong with my body. The exam center was cool, and I was stressed out but 4 times?. I think the mid session breaks lasted almost 2 minutes each. That's a whole question's worth of time on each section.
Weirdly did well on the essay(I felt I did) and got a 7 on IR. I had practiced only 1 IR section and 1 essay previously. I wish they were at the end. It is idiotic that they start you off with the least important stuff. Will be retaking in 17 days since I have a deadline on the 1st of March. Wish I wasn't in this position but oh well. At least I learned a lot. I BELIEVE i'm 700+ material so I'm going to try to achieve some zen and mental stamina/strength along with some further practice.
