I've scraped by with 71%. I'm relieved I passed but my other results have all been over 90% so it's not great. I booked a resit weeks ago so I'll try again this coming week but can't imagine I'll do much better.
Thanks very much for the replies. I'm 51 and was a bit worried about feeling like I'd stick out like a sore thumb going into exams with some youngsters so you've eased my mind a bit. I'm also stuck in a bit of a rut in my job and hoping this can help me move forward.
