Remaining calm during online tests involves preparation, attitude, and surroundings. Start with a good study routine that does not involve last-minute cramming, which tends to create anxiety. Get used to mock tests to develop familiarity and confidence. On the day of the test, have your environment free from distractions, with a good internet connection and required tools at hand. Deep breathing, staying hydrated, and positive affirmations can also contribute to remaining calm.
Although some students would be overwhelmed and would consider hire someone to take my online exam, it's much more satisfying to establish confidence through genuine effort. Learning to develop the ability to handle pressure and stress increases performance as well as enhances fundamental life and career skills in the long term.
