At the end of the day it’s just you and Cognito

Very helpful, thank you. I am learning all this in my 30s, math has been holding me back from having the career I want. I am hoping I can learn all this so I can get my bachelors degree, and eventually my masters. I do not want math holding me back from achieving my career goals. We've got this, don't give up.

Thank You for making this channel, Cognito is a lifesaver! My grades actually increased when I started watching your videos in maths. from 3 to a 5! :)

You should make a tiktok account. Mention main ideas and terms in a 30 seconds video. You deserve to be more popular. I hope you consider this.
