Best Free Tutorials

Hi everyone. I was hoping for some pointers. Currently in a software development program and don't have the best teacher and the program itself isn't well done either. I have a learning disability and just simply reading something doesn't do it for me. I've found watching tutorials and doing them repetitively is the most effective way for me. Does anyone have any recommendations on free tutorials? Whether it be on YouTube, udemy, edx etc? I just need a program to show me a concept then walk me through doing it. Thanks.
