12 units was the sweet spot for me. I was able to digest and master the material because I had the chance to put in the necessary work to truly understand the material and still have a life outside of school. I decided to take more classes (21 units or 7 or 8 classes) and although I was still able to get very good grades (graduated with about 3.8/4.0), I wasn't able to master the material and I had no life outside of school.

> I was racing to graduate and get a job

This is also why I increased the number of units that I was taking.
