    My favorite things about these videos, aside from them being immensely helpful to someone who hasn't taken a math class since 2012, is the authentic feel of the classroom; disruptions and all! Makes me feel like I am in high school again every time I watch these videos.

      If you ask me, he should have edited that part out. Not sure how difficult that editing might have been, but disruptions are not relevant and are at least somewhat private to those physically in the class.

      I took calculus in high school but didn't go to college until 6 years after I graduated. After 6 years you get a little rusty with things you don't use every day. I also have always excelled more in statistical analysis rather than algebraic formulas. The high school curriculum also serves as more of an entry-level gateway into the collegiate curriculum. Not to say that the course work isn't difficult, but it's definitely nice to have a teacher in the classroom. I took all of my math classes online and taught myself. So as much as anyone would like to laugh about someone in college finding help with algebra online remember that we are all here to learn.
