Transcribe the dates of your exams into your Google calendar and set reminders! 

If you miss an exam because you forgot about it, there is no comparable available!

If you do not turn up to an External Assessment (EA) and cannot supply evidence of illness or misadventure, you receive an NR = No Result for the EA. 

NR in your subject results means you have not completed the required assessment and cannot be awarded QCE credit (2 QCE points) for the subject. A comes with a loss of 2 QCE points AND could put your QCE in jeopardy!
