EdX has carefully designed assessments that are accessible to screen readers. However, because of a limitation with HTML and screen reader technology, you may not be able to read all math problems in edX problems using a screen reader.

To access math problems with a screen reader, use one of the following methods.

- If your browser and screen reader both support MathML, specify MathML as your preferred math renderer in MathJax.
- Switch from your screen reader’s Interactive mode to Reading mode.

**Note**: Your screen reader may use different names for Interactive mode and Reading mode.

- In
**Interactive mode**, use the Tab key to move from one interactive element to the next.

- In
**Reading mode**, use the arrow keys to read all of the content in a document, and not just the interactive elements.

For more information about how to make sure that your screen reader reads all available content, see the instructions for your screen reader.
