In my 17 years of working as a math teacher, I get the privilege of meeting some really special teenagers. Today I met one! AP Calculus AB teachers and students: this 16-year-old is taking the class and creating tutorial/solution videos for her classmates so that they can all rise together. I commend Elizabeth for her benevolent work; her content is thoughtfully succinct, creatively formulated, completely consistent and standardized, and remarkably organized with multiple examples. If you’re taking AP Calculus AB, you need to watch her videos! Please share and subscribe to her Youtube channel to help her out and to get the most out of the AP!
Here is an example video of the 50+ videos she has made.
