How to rank college math classes from easiest to hardest?

I'm planning on majoring in something related to Mathematics in college, but I'm kind of unsure about the difficulty level of different math classes. Could anyone provide a ranking of math classes from easiest to hardest?

Sure, I can definitely help outline which math classes are typically understood to be simpler or more difficult, though keep in mind this may vary slightly depending on the school and individual instructor.

Firstly, introductory math classes or those that serve as a general education requirement for non-math majors are usually more straightforward compared to more advanced classes. This would include classes such as College Algebra and Statistics for Non-Majors.

Moving a step upwards, we have the basic prerequisite classes for math or other related majors: Calculus I and Calculus II. Calculus I introduces the fundamental concepts, and Calculus II dives deeper into these ideas and introduces new ones such as techniques of integration.

Next, there's Multivariable Calculus and Linear Algebra. Multivariable Calculus extends Calculus I and II to higher dimensions, while Linear Algebra studies vectors and linear transformations, which are essential for many fields such as computer science and engineering.

Intermediate math classes often include classes such as Differential Equations and Real Analysis. Differential Equations can be crucial for physics and engineering while Real Analysis is the rigorous underpinning of Calculus where you'll prove many of the theorems taken for granted in earlier classes.

Higher-level courses include Abstract Algebra, Complex Analysis, and Topology. Abstract Algebra studies structures like groups, rings, and fields, and it's a vital part of number theory and cryptography. Complex Analysis extends calculus to complex numbers while Topology studies properties that are preserved under continuous transformations. These are typically considered the hardest as they require a deep understanding of numerous different mathematical principles and theory.

Keep in mind this is a general scale. Difficulty can vary based on factors like your personal strengths, the professor teaching the class, the textbook used, etc. Always make sure to review the course syllabus and talk to students who have taken the class before making a decision.
