Big 4 ICAS contract termination/leave early


I’ve recently started work at a Big 4 firm where I will be studying the ICAS syllabus. I understand that the exams are very tough, Does anyone have any experience of what options are available if your contract is terminated early? As I understand it you cannot start another ICAS training contract with a new employer.

I don’t like the idea of studying accountancy for a few years then being left in limbo after failing some exams. Would it be possible to find employment in a different finance related role such as banking?

Any advice would be much appreciated.
