About omegaUp
Its content runs from beginner courses to olympiad-level problems, so it suits Spanish-speaking students and teachers. Teachers can create their own courses, contests and problems for a class.
You use it in the browser at no cost. A U.S.-registered nonprofit runs it, and the platform code is open source under the BSD license. In early 2024 it had over 9,000 public problems.
