I will make a video explaining how to solve any high-school math or physics problem

If you have any high-school level math or physics problem I will make a video of me solving the problem with pen and paper while explaining what I'm doing, why and how I think when I solve that kind of problem. In the video you will see the the pad and me writing on it to solve the given problem. I am an engineering physics student in my third year of university so I should be able to explain any type of high-school problem quite well.
