The Periodic Table will always be available on any exam or quiz.

You will not have the list of rules for the exam. Therefore, it's in your best interest to learn it as quickly as possible.

You will also not have the formal charge formula available for the exam so you need to learn it.

Once you've opened the quiz window for the first time, you don't need to close the window before asking for a new, random structure. All you need to do is switch back to the main quiz window and ask for another quiz. It will appear in the same quiz window as before.
