A readable summary every week — accuracy, categories practiced, what improved, and where to aim next.
Reference PDFs — lab values, medication safety, prioritization — with a clean layout and cited sources.

The math
Re-registering for the exam is $200, and most boards make you wait at least 45 days before you can sit it again. Scruba Pro is $60 for the year — the whole bank, the timed exams, and the plan that's built to get you through on the first attempt.
15 questions, no account, no card. If the explanations don't make it click, you've lost nothing.
