Been told by Skyborne that there will be between 8-12 candidates on each course, with courses commencing in March, April, May, July, August, September
Also on the number making it to the final assessment - I am reliably told that BA were initially planning to bring c.150 to the final stage (from both FTO combined) when there were 70 places. I cannot imagine they would lower that number to the 120 calculated above especially when there are now more places. I am operating under the assumption that there will be 16 candidates on each day, so 240 total left. Another piece of evidence which points towards this is the "Networking" section of the information doc which states "It is important that candidates do not discuss the activities with each other". This to me implies that there will be 2x groups of 8 sitting the different sections at different times.
I could of course be completely wrong as well! But as I say, can't imagine they'll have lowered the number of candidates whilst increasing the number of places.
