I used the course on Linux Academy, plus an Anki deck I found in the list of shared decks. That, along with making up a bunch of questions in an Anki deck myself, using the FAQ pages for the various AWS services, was good enough to pass comfortably. That said... The test is not easy. I studied pretty hard and have a considerable amount of real world experience with AWS, and I was honestly a bit nervous when I got to the end of the test. I usually try to over-prepare for tests like this, and usually expect to go in and score pretty close to 100%, and on this one, while I had no problem passing, I wasn't even close to a 100% score. Take that for what it's worth.
