Hi Joey (or whatever is your real name)!
I also took The Rescue Remedy Spray. My Friend was actually suggesting the tablets one but I decided to prefer this one. My friend said the tablets made her really calm (she said she was worse when nervous; gets sick). As for my spray, I'm really not sure coz I use it when Im nervous and still no effect. Yet, in the test it didn't mess up with me, although I know I am still nervous.
I also found some videos in youtube abt holding up your nerves, try to check them and might help you. One is a way of deep breathing and holding it weirdly for 10-30sec.
Have you taken your test?
