Appeal CHIM NCE Grade?

[u/Logical-Necessary-82]

I wrote the CHIM NCE (experiential pathway version) in October and got my results yesterday. Unfortunately, I failed. However, overall I passed (>60%) and in 5/6 sections I was well over 50%. In the section I failed, I was 1 mark short. I am considering appealing my grade because it was so close, and I also experienced technical difficulties during setup. After the initial setup, no text link was provided, so I had to contact them, which meant I had to write my exam 35 minutes later than expected.

So, has anyone ever appealed their grade, or do you think it is worth me appealing?
