With my test date approaching (3 days, 23 hours, ~24 min), I've learned a very valuable lesson about myself during the quant..
and that lesson is: Never let yourself become cocky, no matter how easy the question may seem.
I did a bunch of quant questions in OG this week. I got most of them wrong. The problem was not that I didn't know how to do the problems, it's that I wouldn't read the question carefully enough or become overconfident thinking that I "knew how to do this type of question" and in the process overlooked carrying a 3 over to the next line.
The result of looking over my work was that I have become paranoid, and I don't trust myself anymore. I'm going to scrutinize myself even more now. I also have a problem in reading the question again after I come up with the answer, although I've become better at doing so.
