You need to look into why you have failed these exams, Is it your study technique? Have you signed up to Bristol feedback questions? Which helps a lot by the way.
If you are distance learning, like myself, you need to set yourself a realistic time frame to complete the exams. At first I just wanted to get them out the way ASAP and rushed through the course material. This resulted in me not digesting the information and barely passing my first phase exams.
In regards to jobs, If you were integrated you could forget the BA interview, but in the modular world I would hope it wouldnt mean too much in terms of jobs, just dont fail anymore exams and pinpoint where youre having problems, Speak to your tutor also if youre DL or residential.
