Which is better for IB/AM graduate applicants: IMC or CFA?

I've got a few months before my MSc program begins and i was hoping to take some entry-level qualification to show my passion and interest in finance. I've shortlisted the IMC and CFA. Given that i only have 4-5 months before the CFA lvl 1 and a significant bill to pay if i do decide to take it, im leaning on the IMC. Even though im aware that the CFA lvl 1 is far more thorough and prestigious than the IMC, Im only really trying to highlight passion and interest more than anything else. Is it useful to that effect or should i just do the CFA instead?

Plus, ive heard (both on these forums and outside) that having the CFA lvl 1 prior to application is not seen as a major game-changer by banks (as opposed to work experience, grades or extra-curriculars), and that some would actually rather train their own bankers/asset managers.

All advice appreciated
