    Right now I'm in a chemistry class with a professor that means well, but since the class is only 50 minutes, she's forced to rush through all these concepts and lessons without giving much time for us students to really get a grasp and practice on how to solve specific chemistry questions and the different scenarios we might see. These lessons truly help man, being able to come home and look up a video and finally be able to pause and replay and take my time to ACTUALLY learn these concepts are a miracle.

    I've officially graduated from Tyler's videos. I'm starting chem 2 on Tuesday but you don't make videos for chem 2 :(. I'll stay subscribed though because I have hope that we'll see chem 2 vids pretty soon! Is there anyone else on RUclips who you can recommend and with your teaching style? Thanks

    My Chem teacher gave us just a quick test on Oxd number without giving us any of the numbers to find the oxd no of the elements. I was upset because he never taught us how to find oxd no without being given the oxd no of what we will use to find them
    So I just have to keep that rule in my mind
