In the letter it states theres a 'Respiratory Test' and they've allocated 30mins for it, just from experience is sounds like a step test- theres a box you have to step up on in time with beeps on a tape, you wear a heart rate monitor, the beeps get closer together as the levels increase. They record your heart rate at each level. I'm not 100% sure if this is the test but this is what it sounds like. Please no one hold me to this it's just an educated guess really. If it was just a spirometry test (thats the one you blow into a tube and they measure your lung capacity) they wouldnt need 30mins.
BT085 - yes it was my first attempt, however, prior to leaving the UK 14 months ago i was a full time operational firefighter and had been for 6 1/2 years. I'm 31. Don't throw in the towel yet, my opinion is the emails today are only referring to those that have been allocated a place on the 1st training course.
