I have the distinction of being flunked in Latin I by the SAME nun that flunked my mother some 40 years before me. I then got transferred into a different class, and took 2 more years and did well enough so that it helped with my French all through college.

Though I never took any Spanish classes, I was able to muddle through French, Spanish, and even Italian contracts just with the French and Latin background. (In my industry all the contracts said pretty much the same thing so it wasn't that difficult). I don't claim to have made literal translations, but I got the gist pretty well, and knew when I would need a better translation of particular clause.
