Hi Necky
I can speak first hand for both schools. I originally signed up with Bristol as they had the image and atmosphere which I thought would be best for me. Unfortunately after studying for 7 months there I had only managed to pass 6 of my ATPL subjects, not because I wasnt studying but because I wasnt getting much help from them unless I was made of money. I then thought it was time to look to other areas so that I could finish my exams quickly and get on with the flying. I arranged a meeting with Cranfield Aviation Training school and told them my sittuation and what I was aiming to do. They were completly supportive and took me under their wing. Three months later I had passed all 14 of my ATPL exams and was on my way flying. They are so focused on your needs and hep you in any area at any time to make sure you pass the exams not just at a 75% level (which is a pass with the CAA) but well beyond to make sure that you pass first time and never have to do them again. Please take my experience as advice and go to Cranfield Aviation Training School. They made me so compfortable and relaxed about my exams that it was a shame to leave.
Many people on here would agree with me.
Its only advice and the decision is yours in the end, I just thought I would give you a bit of insigt into what ive ben through
