Hi Mr. Pavelchak,

yes, we are 100% sure that our AP Physics course is a college-level course since our regular Physics course is for high school. And also when you were taking the AP Physics course there was way less advanced technology and it made it a bit more challenging to solve those problems and that is why it may seem to be "less complex" while they are definitely college level. Thank you for your suggestions.

Hope this helps and if you have any additional questions, feel free to ask.

Adding to what you have asked Jossey Joseph an introductory physics course depends on your university and the level you have. For the people like me that did not study in highschool, we started with this physics courses the first year of college. They are only algebra based. Now, in good universities and in other countries, commonly, the introductory courses are like Physics C I or superior. They involve single-variable calculus and if you are in a competitive university maybe you also have to know Calculus II (involving Mclaurin series or whatever). 

Now, knowing how to do the dot product doesn't imply knowing Linear Algebra by any mean. The dot product is commonly tought in Analytical Geometry. But it may depend also. I don't think in a first year class on Clasical mechanics or Electromagnetism course you will see differential equations, but you can develop your experience in order for me to learn. 

And no, KA doesn't offer AP Physics I C. The best recommendation I guess is to buy a textbook or to attend classes at a university or community college. Anyways, if you don't remember very well physics, contrary to popular belief, I think this courses are great. They give you a first glance of the conceptual understanding you need behind the physical ideas. At the end of the day that is one of the characteristics that make it different from math. If you are experienced maybe you don't have to spend too much time on it. I highly suggest it, and although they do not explain in much detail the why behind, I think it's fantastic as nearly all what KA does.
