Even though it looks like a game, the tasks are not games but an assessment of your natural traits. Do not presume you know what to do, even if you are an experienced gamer. Read the instructions carefully before starting the task.
Practice the games beforehand, and understand every game, what stands behind it, and what traits it measures.
Set up a quiet and comfortable area where you will not be distracted and disturbed. Ensure your keyboard is working properly and your Internet connection is stable.
The eventual goal of the Arctic Shores game is to find out whether you are a good fit for a particular job. That will influence the way you behave in games. Remember that the level of emotional intelligence, risk-taking, drive, etc., expected from you will depend on your job, so there is no “one-size-fits-all” to pass the Arctic Shores test.
