Hi mate.
I sat my assessment a couple of weeks ago and did all 7 elements.
GBT - Done on paper with my TOC, left to right.
TRP 1 & 2
Part 1 - Listen to a recording about the application of GLOP whilst reading the same info from a card then answer something like 18 questions in 7 minutes. Very straightforward, normally enough time to go over your answers again before time runs out.
Part 2 - Dials and Cables test. Dials are split into zones of priority marked by different shaded 'zones'. There are arrows in each dial. On outside of each dial are numbers. Task is to decide in which order of priority the dials must be arranged. Simple rule is to look at the arrow first to ascertain which zone is more important then look on outside at numbers - lower the number the more important that dial is.
Very straightforward once you understand what is expected of you. 8 mins to answer 43 questions, you're not penalised for wrong answers either.
DFFT - Cant help as not required to sit this for my TOC. (Strange... Wonder why?..)
TEA-OCC
Part 1 - Required to listen to audible tones, low and high and have to count the total amount of low tones.
Part 2 - Required to search through a fictitious phone book for matching symbols. Information read out at start of test meant to throw you off, your task is only to circle/mark pairs of matching symbols.
Part 3 - Required to carry out Part 2 again whilst listening and counting audible tones of same pitch.
Both Part 2 and 3 were done going from top to bottom.
Hope that helps and best of luck!
