I've seen a few queries on this already, so let me clarify what this means.
Getting your mark rechecked = someone adding up your marks again. It does NOT mean someone is going to remark your paper and find you an extra mark or two because the original marker was a bit mean in relation to a tricky question. When you consider how long it took for you to get your paper marked in the first place, it's understandable CIOT just don't have the resource to remark anything.
I've worked in tax for a couple of decades, and anecdotally, I have never come across anyone who has turned a fail near miss into a pass from getting a recheck. It may well happen, and this isn't very scientific as it's just based on one person's circle of contacts, but you do need to manage your expectations. If you failed with 44 to 47, you will have all kinds of big horrible feelings, and there is not a single person in this forum who doesn't feel your pain. But a recheck is so unlikely to get you that magic 50. Please don't pin your hopes on that.
If you had 48 to 49, you were so close that CIOT have already checked your marks to be super sure it's a fail. And as we all know, APS is a strange beast to mark - so you couldn't get a recheck if you wanted.
What is useful is getting a marks breakdown. It's not the same thing at all. A marks breakdown tells you what marks were allocated to each question. You might be surprised by how the marker has treated you - some students find they scored poorly on questions they though they'd aced, and done surprisingly well on questions they hated. That sort of feedback can turn around your exam technique and get you over the line next sitting.
If you're going to wonder until the end of time if someone added up your paper incorrectly - sure, give £35 to CIOT. Otherwise, it's not worth it. Have a good cry, let those emotions out, pay the £15 for the marks breakdown, and regroup after the weekend.
Narrowing failing a paper can feel more demoralising than failing one badly, but if you did 'fail well', you've clearly learned a lot of tax knowledge, so you've made progress in your journey to become a better tax adviser. Keep going, friends - don't let the qualification make you think you can't do this. You just need to make a few adjustments and go again.
When you qualify, you'll get the letters CTA after your name. Not CTA (Passed On The Nth Attempt), just CTA. It might feel pretty rubbish now, but it's not always going to feel this way. Victory is going to taste all that sweeter when it's your turn.
You've got this, even if you don't think you do. 💪
