Somewhat long story time.

Because I moved from a different country to the US they got confused what grade to put me in. And then they really goofed my class assignments. So I ended up literally only taking algebra 1 and geometry in high school. Unlike most that also got algebra 2 and possibly trig.

This set me up supery poorly for college. But I’m actually really good at math and I love math. So when I got to college, I failed miserably and dropped out after teachers were telling me this was simple stuff I should know from high school trig. How the college even let me get to that point was also insane…

Anyway years later I went back, they tested me and I needed remedial math classes. Finally this new college was doing it right. I immediately started failing my tests. The teacher actually cared to find out why. I was getting every answer correct, but I was only finishing about 50-60% of the questions. When they looked at my work they noticed I just want using the right formulas in the right places or the common shortcuts and such. At they focused on teaching me that stuff all of a sudden I was actually finishing my tests ahead of class and passing.

Math is weird.
