Overall, the course itself is composed of different topics integrating the knowledge about how to solve different mathematical expressions within the scope of simplifying as well as determining where those given expressions come from. From that, we can easily come up with the desired outcome. That makes the idea of mathematics challenging as well as interesting.
I can't say the course for me was easy just because of what I learned before but to be honest, for me it's challenging because of how the topics are being relied on here. Just to share, I also joined math contests when I was in junior high school and was able to gain certain awards because of that. That helped me to be challenged here because of the intricateness of topics which makes it interesting to learn. Putting everything into account, learning this kind of subject does not only entails memorizing different formulas but also knowing the scope of these formulas.
