I think the STS questions are a wise investment even for a seasoned DBA. It will prepare you for the exam questions format which, let's face it, is intentionally tricky. I think for that alone it is worth it, especially with the discounts that have been offered recently. I have been duped many a time with the STS by going for the first answer that looks correct, or rushing, or both. I think it is also a good idea to get in the test “groove” so to speak, just getting used to sitting down and banging out 60 questions on a regular basis is good practice.
