Yeah,don't over think things,the basics remain the same...so use and apply them.
My 2391 invigilator,had the C&G assessor,watching him,watching me...i dislike scrutiny,on a good day,but it pressed me harder than me first borns' tricky birth :rolleyes4:
Having been the instructor and assessor,myself,you get to realise,that nobody is in it to trap or catch-out folk. Most of these individuals have come through the job,and will generally "will",the assessed ,to succeed.
Stay calm,work methodically...and move on to your next goal.
Good luck,and if you feel like it,let us know how you fare :smartass:
