30 LIVE: Combinatorics
Ma/Mi/J/V/L 9:00–10:30pm desde {{firstDateM}/{{firstDateD}} (hora del Este de EE. UU.)
El curso de LIVE tiene un total de 30 horas de formación de video en vivo (~20/hora), más 1 año de acceso a los videos pregrabados del curso del Prof. Loh.
We’ve carefully designed our courses to maximize engagement. Each of our LIVE classrooms has at least one staff member for every 13 students. The typical class size is around 30 students.
* The official meeting time for this course is 5:00pm in New York.
