A good chunk of your assessments are either a non-graded pass (NGP) or on a scale of ‘unsatisfactory’, ‘doubtful’, ‘satisfactory’ and ‘exceptional’. You will receive an actual grade for weekly iRAT assessments.
Getting an unsatisfactory or doubtful can be pretty disheartening, especially if you are use to achieving high marks, but make this an opportunity to complete remediation. Remediation is not a bad thing; it is an opportunity for you to improve on your knowledge, and you will likely end up learning more and remembering it better.
You can always self-remediate, don’t wait for teaching staff to contact you! Lastly, an iRAT grade does not always represent your knowledge, so don’t be too disheartened if you get a lower grade than expected when you studied hard during the week.
