AIBU to avoid doing an exam due to risk of failure

[Namechangedtoprotect]

I have to do so many days of training for my job and I found an exam course to improve my skill set. It's home study and exam. I've failed the exam twice and am too scared to try again. Work paid so I feel guilty but the feel of rejection has got me paralysed to even start. After the last failed attempt I have waited a month to sort out other parts of my life. I've picked it up today and the same feeling of dread and fear is back. Do I walk away and relay the cost of the course (a few hundred) or keep failing forever (I need to pay for retakes). I've always been good at exams before but this is beyond me.

What is the course? Are you failing badly? Are there any tutors you can ask for advice?

Pointing out the obvious if you don’t go then you’ve got a 100% chance of failure, you could at least try otherwise it really is all for nothing

There are no tutors, it's like a refresher course so in the grand scheme of things it's reminding me of things I learned 10 plus years ago when I did my professional training. I know it all and can apply but in the exam I forget everything and panic

So its actually exam nerves that are the problem? I wouldn't normally suggest hypnotherapy but if you can find someone reliable it might help.

I got over my exam nerves by sitting a 20 minute mock exam every evening.

There is one mock which I have done to death and can pass easily. The questions I the real exam are much harder.
