+All classes under Core Mathematics are **required**, unless stated otherwise.
 
 ### Introduction to Mathematical Thinking
 Most people's views of mathematics are destroyed in school by focusing on memorization and regurgitation. But mathematicians see math as an elegant way to explain the world around us. This class covers how to think like a mathematician and solve problems.

 ### Calculus 
-Calculus is the study of change and accumulation of quantities, specifically rates of change and the properties of functions. As the cornerstone of geometry and physics, it serves as the foundation for understanding many natural phenomena and plays an important role in modern technology, scientific discovery, and many fields including engineering, economics, and medicine.

 ## Advanced Topics
 
-Once you've completed all courses in Core Mathematics, you are free to take elective courses in Advanced Topics, which include:
-
-- Differential Equations
-- Mathematical Logic
-- Geometry
-- Probability and Statistics
-- Mathematical Analysis
-- Abstract Algebra
+Upon finishing **all the core mathematics courses**, students can choose to take elective courses in advanced topics of their choice. It is not necessary to take *every* course within a subcategory, but it is recommended to take courses relevant to the intended field of study.
 
 To complete your study of Advanced Topics, complete both the Breadth requirement and the Depth requirement.
