To be honest, learning to play on different pianos is part of the skills a pianist needs to learn, unlike any other instrument - we have to able to adapt to whatever piano we play on. The exam piano will probably have been approved before the exam as suitable for candidates to take their exam on. Some exam centres even allow candidates to have a go on the piano before the day of the exam. (Obviously not all.) I doubt the piano was the cause of failure in itself but it may have put you off. One of the best things is to get used to playing on as many different pianos as possible - friends, school halls etc. To go out and buy a Yamaha seems rather drastic and expensive, and if the one in the exam venue changed for any reason (and pianos can also change slightly as they mature and age I believe) you'd still have the same problem. It's just one of those things we have to get used to as pianists.
I am lucky enough to do quite a bit of my playing on a Steinway B

and my home piano is a pretty good upright.
However, when I took Grade 6 the piano at the test centre was an absolute disgrace. Out of tune, clearly never properly regulated or maintained and with various sticking keys. I set off in my first piece and promptly came unstuck - the top note of my first run just didn't sound. I started again and it happened again. The examiner came over and took a look, and was quite sympathetic, and told me to start again and persevere. Which I did, though it was absolutely no fun at all.
Luckily I got a high Merit, otherwise I'd have appealed. What's worse is that this pile of firewood is still being used for exams. Needless to say, for my Grade 8 I've asked my teacher to find me a test centre with a better piano.
Having said the above, it's true that a pianist should be able to play on any piano.
