High School Geometry!
Since I am taking business courses and planning to learn Python, I would like to get my math skills back in order. Before being interrupted by COVID-19, I completed the high school Algebra 1 course at Khan Academy and started the Algebra 2 and Geometry courses.
To keep life simple, I’ve decided to focus solely on geometry. As with the Algebra 1 course, I’ve bought a couple of workbooks with extra practice problems.
I like Khan Academy’s instructional videos. If these had been available in high school, I could have finished the course in half the time.
