Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)

Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”

Your videos are helping me get through Cal 3 right now. It is incredible how long ago this was posted but is still helping people like me. Thank you, Krista!

I usually stick with videos from JG ochem tutor and Kahn Academy but I was very impressed with your explanation. Keep up the good work!

Thank you so much Krista! You helped me get pretty good grades at the University Level in Discrete Math and now Vector Calculus this semester. You have no idea how much your videos probably help so so many students!

Much more helpful than the official Larson homework help, even more so than the given solution to my odd numbered problem. Thank you
