So a very strange thing happened in my recent GMAT attempt. The night before my exam, I went to bed at 11 pm but couldn't sleep till 1:30-2:00 am. My sleep was interrupted at 7 am from some noise outside my apartment, and unfortunately I couldn't sleep at all after that. My test was in the morning at 11 am so I got ready and headed to the test center. I tried doing a few Quant questions for warm up before the test. It felt a little weird while I was solving some simple quant questions- I felt like I wasn't able to do simple basic calculations. I ignored all that and tried to stay positive.

I opted for Q-V-IR-AWA order. As soon as quant started, again I started to see that I was having a really hard time doing simple questions. I literally couldn't focus at all and ended up skipping a LOT of questions. My final quant score was 45. I knew I screwed up my quant section but I still tried to remain focused on Verbal. Again I was having a hard time comprehending some really long RCs. As a result, I performed really bad in RC, which is my strength. I ordered ESR and I got a RC 27, with a V 31 and 620 (Q45,V31) overall score. Even in MGMAT CATS my lowest score was 660, so this is really disappointing.

Can lack of sleep really drop your score by more than a 100 points?

Hi yt770,

It could be that you just had a 'bad day' - you're not the first person to have a poor night's sleep before his/her Exam and perform worse because of it. To be proactive about all of this, you now have to consider how you might adjust your routine so that this type of issue doesn't recur and hurt your performance when you retest.

GMAT assassins aren't born, they're made,
