Starting the 2025-2026 school year, McLean will be offering a new math course on Differential Equations and Discrete Math for current juniors in Multivariable Calculus and Linear Algebra. The class, currently taught at George Mason University, will include more difficult math content than McLean has offered in years previously.

“Students either need a C or better in Calculus 1 & 2 DE or a qualifying score on the AP Calculus BC exam—I believe it’s a 4 or higher required—and it can only be taken after students successfully complete Multivariable Calculus and Linear Algebra,” said math teacher Ginnie Quarry, who will teach the course. “It is really exciting that this course is now offered for students who complete Multivariable Calculus and Linear Algebra as 11th graders.”

Students enrolled in Multivariable Calculus and Linear Algebra are excited to be able to continue learning math at McLean.

“I plan on being a math major when I’m in college, so I’m trying to take as many advanced math courses not only to look strong for colleges but because I’m genuinely interested in advancing my knowledge in math,” junior Joshua Massery said. “I was planning to take Differential Equations at George Mason, but taking it at McLean High School makes it much easier to access.”

Many seniors currently taking Differential Equations at George Mason recommend the course. 

“Differential Equations helped me understand how we are able to model a lot of the trends and natural phenomena occurring in real life, and it is useful in physics,” senior Callie Liao said. “Students are lucky to have this offered at McLean — even though taking it at a university sounds exciting, it has made me grateful for the readily available support I could get from my teacher and friends at school, so take advantage of this opportunity.”

However, some students find Differential Equations tedious and too abstract for real-life applications. 

“Think about how you experienced Multivar because it is going to be a GMU class again,” senior Twig Batish said. “If you liked the style of the class in Multivar and Linear Algebra and you want to continue, then that’s good. If you really struggled with the college format of it, then don’t take it again because it’s probably going to be harder for you.”
