You can add a variety of problems, exercises, and tools to your course outline.
By default, a core set of :ref:`problem types<Working with Problem Components>`
is available in Studio for you to include in your course. You have the option
to expand the initial set of core problem types by enabling additional
exercises and tools.

Enhancing Your Course with Additional Exercises and Tools
*********************************************************

"Exercises and tools" is a general way to refer to the robust variety of
content that you can integrate into an online course. Software developers use
the XBlock component architecture to contribute new exercises and tools to the
Open edX platform and provide new and varied options for reaching learners.
Exercises enhance the core set of problem types by challenging learners to
complete graded and ungraded assessments. Tools deliver a variety of other
types of course content.

* To use an exercise or tool in your course beyond the core set of problem
  types, you must explicitly enable that exercise or tool. For more
  information, see :ref:`Enable Additional Exercises and Tools`.

* After you enable an exercise or tool for use in your course, you might need
  to select **Advanced**, **Text**, or **Problem** on the unit page to
  add content of that type to your course.

The topics in this section introduce the core set of problem types and a
selection of other exercises and tools that you can add to your course.
