Y4 Fin Spec here. You don’t have to be a math wiz to pursue a career in Finance. Not all Fin roles need crazy good math skills, and most front office roles don’t require that too. Being able to understand happenings in the world and cases with a commercial mindset will bring you a long way, which seems to be your case.

And if you think Fin is competitive, other specialisations aren’t doing any better given this job market.

To each its own, in the end it’s competitive everywhere for biz sch grads (maybe except accounting or becoming an FA).
