You've taken the time to prepare and now you're here! Your instinct will probably be to just start answering questions but there are a few things to think about. You want to reduce your stress or anxiety as best you can by preparing and being strategic. Try these strategies:
Breathe and stay calm!
Manage your time – set an alarm to indicate the last 30 minutes
Have only required and permitted materials with you
Read over all the questions on your test and evaluate each (e.g. does it require you to just answer facts or require you to analyze, elaborate?)
Answer the questions you know first without using your notes
If you are struggling on a question, mark it, move on and come back to it
Don’t plagiarize – write your answers in your own words
