STEM competitions cover math, science, engineering and computer science, from school-level contests to national olympiads and science fairs. Some are taken alone in a single sitting; others are team builds that run for a whole season.
Start with contests your school already registers for, then add one that matches a project or subject you are deep in. Many national competitions have a qualifying round first, so the early deadline is usually the one that matters.
