Should I leave B4 ACA apprenticeship for target universities?

Hi guys, I'm starting an audit ACA apprenticeship at B4 in September and will also be applying to target universities (Warwick, UCL, Imperial etc) for 2027 intake. I'm not entirely sure what i want to do in finance but money is a big motivator for me. I feel IBD is interesting but awful hours and culture. ER and AM interest me very much though. If these were my main goals, would you guys recommend leaving B4 after 1 year to go to Warwick/UCL for Economics? I'm aware B4 --> TAS --> M&A is a possible pathway but I feel none of the exit opps from IB interest me that much and hours in IB can be awful. Thoughts?
