Indeed, you have done a great job.

Suggestion: Please write about the prerequisites below the course content.

Otherwise what are the prerequisites for discrete mathematics 1 and Linear Algebra.

Thanks a tan for your tireless effort.

The first course in each list requires no pre-reqs. Just need some basic high-school math.

This is going to be great help to learn a lot of this stuff before I take Discrete in the fall semester in college. Discrete will be the hardest math class in the fall so these videos are a great help before I learn it,cause most of my time will be spent understanding Discrete cause I have many other classes to worry about that will be on the easier side like Calc and physics. Thanks for you help your videos make sense and you are a great tutor.
