If a student's cursor in Chromebooks is not aligned where their text, this may be due to browser font being changed to a non-Monospace font. Monospace fonts is when every letter is the same width. The settings can be configured through the browser settings. Click Settings > Appearance > Customized Fonts > Fixed-width font.
We recommend choosing the font Authaya or DejaVu Mono, but any font with Mono is sufficient.
Also check to make sure the Language is set to English: Advanced>Languages and make sure it is set to English (United States).
