If I had to guess, the CAS won’t make an adjustment for one person. I know I ran into some difficulties during my exam and I have heard others had some difficulties too. I couldn’t copy and paste for about 5-10 minutes. I am sure there are other complaints that will be similar.
The only real adjustments I think the CAS could do is lower the the total MQC required to pass. I have no idea how likely this is. My bet is that they won’t do it, unless there is a clear trend in an exam.
I think the CAS won’t release pass marks because they don’t want people complaining. Whether they release how many people took the exam and passed is a different question.
It is very likely you will get the following type of response to your grievance: “We have looked into your issue and decided not to revise anything.” Something generic.
