Ideally, they would be devoid of any marks, so that you give yourself a chance to do the problem again.
Some people are super visual and would have a hard time ever forgetting the correct answer even if they're looking at a clean copy. If that's you, then it doesn't really matter if you already have a marked-up copy. You would know the correct answer either way, so you'd just be practicing the reading/reasoning steps involved in getting through it correctly.
Most people, though, have a foggier memory. You'd probably remember which two answers you were down to before, but not which one you picked or which one was right. Make sure that many of the questions you add to your pile are ones you got correct! A lot of time we get a question correct, even though in the moment we weren't very confident about our answer. THOSE questions are just in need of review as the ones you got wrong. You ultimate measure of mastery is that you completely understand why the correct answer works and why the others don't.
Another option (the paperless Super Pile) is that you just get in the habit of writing the PT _, S _, Q _ information for any question you want to add. You're doing a problem, you want to add it, you write down on your sheet of notebook paper (or a Word document) PT42, S3, Q12.
When you go to do problems in the superpile, you can just open up the pdf for any prep test (they're all in your student center).
If you wanted to compile a clean, printable file, you could open up the pdf in Acrobat, delete the other pages of the document, crop the page your question is on, re-save that question as its own pdf file, and then import that pdf file into a growing master pdf Super Pile file.
Have fun!
