Do you know of any online activities or exercises that help practice Latin vocabulary?

I have an exam on chapters 1-15 of Wheelock's and my vocabulary isn't great. I've done really well on my assignments using my dictionary but I cant use it in the exam.

I'm so tired of translating lines of text. I pretty much just need to work on knowing the principal parts of verbs and pounding the other vocab into my head.

Any help would be appreciated.
