I make maths and science videos for different high school curriculums around the globe. Currently this channel has: 1. CAPS / IEB / DBE South African Curriculum 2. Algebra 2 American Curriculum
For South African learners: Want more videos than on RU-vid? Here is a link to my South African course which contains all the videos! :) purchase.kevinmathandscience.com/299course
