Funny story about the GMAT: I thought I had an appointment scheduled for two weeks from now, but I didn't. I checked yesterday morning, you know, just to make sure everything was cool. Everything was not cool. I did a quick check for anything available and literally the only open appointment was for today.
So I scheduled it (for reals this time) and took the test this afternoon. Sure I had to frantically review the material but it's not like I was going in unprepared. I already had four months to study, after all. I took the day off work to brush up on the basics and go in with a clear mind. And I did really well! ("unofficial" total score: 710)
I don't think I realized the amount of bandwidth this test prep was taking up. Even when I wasn't studying, processing this information was a burden, and now I am relieved of it! All of that useless knowledge can be forgotten once again, at least until (as Jenna pointed out) our kids start learning this stuff in school. Then it begins all over again.
