This course will cover early-to-mid AIME level geometry related to triangles, circles, and trigonometry. Topics include similar triangles, triangle centers, cyclic quadrilaterals, power of a point, trigonometric identities, and coordinate bashing.

This course will run on Saturdays from 3-4pm Eastern.

In this course, we cover common methods in counting and their applications, on early to mid AIME-level problems. Topics will include constructive and complementary counting, PIE and constructing sets, bijections (such as Stars and Bars), recursion, and path-counting.

This course will run on Saturdays from 4-5pm Eastern.

Vieta, trig functions and prime number theories ♪
Mass points, right triangles and coordinate bashing ♩
Manipulation and geometric series ♬
These are a few of my favorite things~

In this class, we’ll be talking about a variety of tricks that are prevalent on the AMCs and early to mid AIME which I find to be particularly elegant or beautiful.

This course will run on Sundays from 4-5pm Eastern.

This course is designed to strengthen students’ counting and probability intuition skills at the early-/mid-AIME level. Students will learn a range of approaches, including constructive and complementary counting, simplification and recursion, invariants, bijections, and strategic bashing. Lectures will be heavily problem-based as AIME counting problems tend to rely on strategies and ideas rather than formulas.

This course will run on Sundays from 5-6pm Eastern.
