Passing tests is not a good indicator for programming aptitude.

I don't think you'll do well at freelancing unless you have some useful skills. Getting paid to learn is unlikely to work out well.

Python is one of the easiest languages to learn and you can be very productive with it relatively quickly.

Javascript is quite a bit harder, but more widely used.

If you are really money focused (your handle is "BizNerd" so take looks like a hint) why are you looking at programming? Sales is very much in demand and a good sales person earns heaps more than an average programmer (which takes at least a year or two of dedicated work to reach).
