Short test or full assessment?

Both use the same item types and the same scoring model. The difference is how much uncertainty is left when you finish — and how much the result explains itself.

Good to know

Can I do both?

Yes, and most people do. The short test is a sensible way to see whether you like the format before paying for anything. If you upgrade later, your short-test attempt stays on your account so you can see how the two estimates line up.
