A study plan weighted to the vendor's own blueprint
Most study plans divide the material by the number of days. This one apportions it by the domain percentages the vendor publishes, so the domain worth a third of the exam gets a third of your time. Put in a date and it works out the order, the daily count and which days to sit the practice exams.
Put your exam date in and this works out the order to study the domains, how many questions a day that means, and which days to sit the practice exams. Nothing is saved and nothing is sent anywhere.
What this does and what it refuses to
Domain weights come from the vendor’s published exam objectives, linked on every plan. Where a vendor publishes a range rather than a figure, the registry carries the midpoint and says so on the certification page.
Studying the heaviest domain first is our rule, not the vendor’s. Vendors publish weights and not an order. It is worth breaking where a light domain is a prerequisite for a heavy one, and the plan says so rather than pretending the order is official.
Nothing here estimates a pass rate, an hours-per-domain figure, or how long “most candidates” take. No vendor publishes any of those, so every version of them you have seen was invented by whoever was selling you something.
Planning the money as well as the time? The cost calculator adds up vouchers, retakes and renewal, with the vendor page behind every figure.
Then work the plan.
Every question is written from the vendor's published objectives, and carries the passage on the official page that the answer rests on.
