Monthly Contest
A contest with several problems with integer answers. Problems may be answered in any order, with a limited number of attempts. Scores are weighted, with a penalty used for tiebreaking.

Online Math Open
The partner OMO contests are based on teams of up to four and give participants more than a full week to solve 30 short answer questions, ranging in difficulty from the early AMC to late IMO.
