Is it worth supplementing my (very theoretical) economics degree with MIT OpenCourseWare?

Hey everyone,
I'm currently studying economics and business in Italy (I'm Italian), and I’m trying to figure out how to better prepare for a career in finance. 

The main issue is that my university is very theory-heavy. We rarely get to work on practical cases, we don’t use Excel, and there’s almost no exposure to real-world tools or simulations. It feels like I’m missing a big part of what actually matters in the job market.

Recently I came across some open courses from top universities like MIT. I’ve started watching a few and they seem way more aligned with what you’d actually need on the job.

I might have found an entry-level job with an insurance broker that provides risk management services to small and mid-sized businesses. On paper, it looks like they focus on risk consulting and helping clients build proper strategies but I’m concerned it could turn out to be mainly a sales role. I’m not against sales per se, but I’d prefer something where I can build analytical skills that could be useful long term.

So I have two main questions:

1. Do you think following these courses (like the ones from MIT) on my own is a good idea to gain practical knowledge and stand out in a job or master application?
2. Does anyone have experience in insurance brokerage specialized in risk management for SMEs? Is it usually more consulting or more sales-heavy?

Any advice would be super appreciated, especially from people who’ve gone through something similar.

Thanks!
