I took my stage 2 and started laughing to myself half way through one of the sections because I was sure I'd gone completely wrong!
The other thing was that I was usually one of the last people finishing a section and thought 'I'm waaaay out of my league here'
BUT I passed and have my S3 next month, so as previously said try not to worry! Hardly anyone comes out of that test feeling like they've done a good job!
Good luck
