Getting started on STEMpump.org

STEMpump is a free library of courses and camps across science, technology, engineering, art and math, written by students. There's nothing to sign up for: open any course and start learning.

A quick tour

  1. Open the Library. It starts on Discover, with today's picks. Choose a subject in its sidebar to see every course and camp in it, or search for a topic.
  2. Start a course. How do courses work? explains chapters, lessons and how you complete them.
  3. Come back any time. The Library's Continue learning row lists the lessons you opened last, and each course page has a Continue learning button.
  4. Save what you like. Add courses, camps and lessons to your Favorites.
  5. Finish a course to get a free certificate.
