What helps students do well on an online quiz

Most students asking how to take an online quiz are less worried about the software than about timing, reading questions carefully and remembering material under pressure. Start by checking the quiz rules: how many attempts you get, whether questions appear one at a time, and whether you can go back.

Read each question fully before looking at the options, especially words like not, except and always.
Keep a short list of topics you missed and review them the day before the quiz.
Check your internet connection and close other tabs before the quiz starts.
Use the practice quiz timer to get a feel for how long each question should take.

Example biology practice questions
