Hi, I did my exam here in Ireland a few weeks ago and mine covered everything.There was 60 questions and I think we had an hour and a half to do it. Re-read all your notes and your manual. Know how to do your prep, know about contraindications, salon hygiene, overexposure, zone sculpting and be able to draw a diagram of the nail and name the parts. Basically everything you've done in your course. Look at it as a positive thing. Its just a test to make sure you understand what you've learned and so you can answer your clients questions and perform a good service.
Im sure you'll do really well. Best of luck. Let us know how you get on.
