How do I incorporate Marxism into a Commerce degree?

Starting a double major in Economics/Accounting in a couple of months. Wondering if any comrades had any advice on how I can use skills like this to further my understanding of Marxism and/or help working-class movements in any way.

btw if anyone's interested I had offers for history and fashion design too but I unashamedly picked this combo for employment (I still enjoy it anyway)
