If the cursor on your Chromebook is delayed or the typing happens a few spaces before your cursor you can try a few things to resolve this issue:
See if other computers in your classroom are having the same issue
Make sure your computers are free of dust and clean
Do a browser reset by going to settings and selecting reset, then restart your computer
If this still does not resolve the problem find out what the Chromebook model and OS version it is using and contact support
