Oh really? I was going off their own FAQ since the graded items requiring paying, and I didn’t want to do it if I couldn’t use the languages I wanted, namely F# and Racket.

From the FAQ:

> > Which programming language do I have to use in order to complete the assignments in this course?

> We expect learners to submit assignments in any version of Java, or Python. We will assume that you have basic programming ability in these languages, including a basic ability to understand and write simple object-based programs.

So is their FAQ out of date I guess?
