Stress is a normal part of studying, but if you don't manage your study load and your other commitments well, the stress can become overwhelming.
Stress is experienced when you perceive there are high demands made on your time, ability, or personal resources, and you also perceive that you have little control over these demands. Your perception plays an important part in experiencing stress, it is a very individual thing and varies enormously between students.
Stress and your study
You can keep your study related stress down by staying on top of your study load. You can do this by using your time well each day, during the week, and across the trimester. You are expected to commit about 40 hours study a week for a full time study load. What you don't do today, will need to be done tomorrow. Don't wait until the assignment is due tomorrow!
High demand for assignments + low control of time left = stress city! Use a daily diary and have a wall chart for the trimester to help you manage your time and stay on top and up to date with your university work.
