How to raise an exception in Racket in an exercise in Exercism?

Programming Racket

In “All Your Base”, I need raise exceptions while invalid parameters are provided.

There are sections on exceptions in the Guide and in the Reference. However, it looks to me like you need not raise exceptions at all, and instead need to return #f.

Super good. Yes. Return #f helped my code pass all checks. Thanks a lot!
