I personally agree with Rex.
But, for the purposes of the FR application, you're right in saying that a partial isn't a fail.
The online form is only the initial bit, the cv will tell them the true story so they will see and understand the actual case from that.
At the end of the day, you are now a proud holder of a CPL and IR, maybe you just had a bad day, we all do, so they may well not judge on the first look and indeed will see for themselves during the assessment.
All the best and good luck.
