Help me do my HW!!! Hang with me for Data Analysis for Engineers

I have trouble concentrating sometimes, so I decided to try something out. I recorded it! I was able to get it done wwaayyyyy faster! Thanks everyone! Im working on data analysis for engineers and scientists - a math class not a programming class. I do a lot of my math with R or python since I graduated so I wanted to refresh my notation skills etc. tell me what classes you take to up your skills! You can see my art on the wall behind! Sorry about the song quality!!
