I decided to just pay for the groundschool at BCFT as at the time I wasn't certain I wanted to stay on and do the flying training with them.
After a few months I realised I had made the right choice and in the end went elsewhere for the CPL and IR.
When I was there (a few years ago now) the groundschool was very good, with experienced instructors who taught well. Only a few of us passed them all first time but this is not a reflection on the staff. You must must must recognise your weaknesses and revise the heck out of them. In the run up to the exams I was putting in more revision than I ever did for school/college and university exams. On exam day I was up at 5:30am revising, going in and sitting the exams and then straight back into revision. In the evening it was a quick bite to eat and then more revision until 10 ish. Rinse and repeat.
The guys who dropped a couple of exams, by their own admission, didn't do as much revision as we did.
I didn't stay on to fly at BCFT as I personally felt it wasn't for me. There were at the time some individuals in the teaching staff who I just felt would not teach me in the way I wanted to be taught. I went on to another school who in my opinion gave me a more professional CPL and IR course.
The thing to remember is that a school is only ever as good as its quality of staff. I'm aware that a few years after I was there some of the groundschool lecturers are still about but others have moved on. The only way to find out what it's like "now" is to visit and chat to current students.
The jetline course is a good way for BCFT to keep students on after groundschool by offering a saving if you sign up to it. I would say unless you are 100% convinced then don't go for it. I passed my CPL and IR first time and in minimum hours, I strongly believe if I had stayed on at BCFT I wouldn't have achieved that, and when additional hours in a twin are needed the final training bill soars and any savings will be eaten into very quickly.
The above is just my personal opinion, some of the guys on my course went all the way through and were happy with the service provided.
