I don't think any of the classes are particularly good ideas, and quite frankly a gigantic waste of time. The finance class because you already have an A registered for finance, and the business law class because, well, it's business law.
I read your other post, and let me put up a piece of advice in big Hollywood sign letters: in your specific case, a few classes are
not going to amount to a grain of sand against your prior transcripts. Perhaps you're thinking that your low GPA is the death knell that you need to somehow mitigate to make it to business school. Your low GPA is indeed a red flag, but I believe you have a much more serious issue which is your inability to construct and deliver on long-term visions.
You struggled in undergraduate mathematics classes (and hey, there's no shame in that!), but you stuck with it instead of reassessing whether it was a great fit. You then parlayed that into a PhD in Economics, when anyone in that program would tell you it's insanely quantitative and will push you to your limits. How much research did you actually do into that career/academic track for you to figure out "just as you started" that you didn't like it? Then, you dropped out (which was probably a good personal decision, but isn't doing your MBA app any favors). To follow that up, you started a business (which is great initiative), but as of yet, have not turned a profit. This is just one story after another of unfulfilled potential and questionable decision making.
MBA programs need killer aces. You're allowed to change your mind from time to time, but you need a track record of delivering on your promise. If I'm an admissions officer, I'm asking myself immediately: will this person even finish my program? will this person excel in my program? does this person have the skills to construct a career goal and do all of the work necessary to land that job in a highly competitive landscape? I don't even care what your math grades were at this point, because I'm starting to question who you are at the core, and that's a big, big, big problem.
If you're going to spend time doing anything, you need to figure out how to combat this issue. Alternative transcripts show promise in the short-term, but what are you able to show about the long-term?
