Search for the error messages and try to modify the code as needed.

You shouldn’t try to memorize anything but try to understand it as you’ve suggested. There’s never going to be a “closed book test”. If you ever need a reminder of some code syntax or how to implement anything you can search the documentation, the web or review older lessons.
