Are you going to Southampton for it. What depot have you applied for.
Had mine a month ago & started with 12 others. Colour vision test first which was ok & everyone passed. Then into the classroom for 3 tests,maths ,scaat & another(raatt ??). Lunch then while they mark them. Only half the people that started made the afternoon cut. Customer service after lunch (19 questions long). Then listen to a CD from a imaginary train driver that had hit a car on a level crossing. Calling the incident into train control,they allow you to take notes & you hear it twice. Then they call you in separately to tell them what was said basically. Bullet points needed really,not the colour & type of car it hit. Lastly the ticket selling & ticket checking test. Out by 4pm if you are lucky. 6 people left in my group at the end. Good luck.
