Most challenging math class in college - What's your take?

I'm a math lover and am considering a major in it when I go to college. To better prepare myself, I'm curious about what the hardest math class is in college. Any thoughts?

Certainly, the answer to this question can vary significantly depending on personal interest, background, and the particular college or university you attend. However, it might be helpful to keep in mind that some widely regarded challenging college math courses include Real Analysis, Abstract Algebra, and Partial Differential Equations.

Real Analysis, sometimes considered one of the most difficult undergraduate math courses, involves the rigorous proof and study of calculus. It requires abstract thinking and introduces concepts of metric spaces, which can be quite challenging.

Abstract Algebra is another demanding course, where you study abstract structures called 'groups', 'rings', and 'fields.' It is quite abstract and theoretical, making it challenging for many students who are used to more applied math.

Partial Differential Equations is a tough class mainly because of the complexity of the equations you're working with. This course tends to involve a lot of applied math and can be particularly challenging for students not accustomed to heavy computation.

Just remember, difficulty is subjective, and your mileage may vary depending on your specific strengths and weaknesses. I would recommend focusing less on which courses are considered the hardest, and more on which courses you find most interesting. Passion for a subject often makes the challenges you encounter more manageable.
