This is definitely one of the best math courses available. Prof. Loh explains the topics in a detailed way, and makes it fun.
This is an awesome course.
The video explanations are crystal clear and the challenges are fun. 5/5 would do again.
I think that this course was an excellent tool to “skim the surface” in the world of Combinatorics!
It tells every way to solve a problem and for problems, you get a turn to solve and get hints!

Inscribirse
Este curso puede ser en vivo o a tu propio ritmo. Es más recomendable seguir el formato en vivo, ya que está diseñado para ser tan envolvente que los estudiantes amarán el desafío. Nunca existió nada así. Todos los horarios están en la zona horaria del Este de EE. UU. y se respetará el cambio de hora de verano de EE. UU. el domingo 6 de noviembre.
Los estudiantes que no puedan ajustarse a nuestro horario, o que ya tengan la motivación, tienen la versión a tu propio ritmo con toda la enseñanza del Prof. Loh sobre el tema. Inscríbete y elige el formato de tu preferencia:
