Caroline,
I took my tests on the 9th March and passed them, the main thing is, take ur time and be accurate with the tests. Don't worry if u don't finish all the questions on the papers, you're not meant to. Make sure u read the ATC booklet, the technical paper does use a lot of stuff out of there.
All in all, good luck with your tests and let us know how u get on!
Brgds
