I wanted this to exist when I was where you are.

Studying for this exam and sitting it was one of the most anxiety-inducing things I have ever done. I felt unprepared and without direction, and everything I had heard about it beforehand was frightening. People were taking it two, three, four times.

What got me was the thought of going back to the drawing board without knowing where I had gone wrong — and then spending another forty-five days doing the same thing again. I still have dreams where I have not actually taken it yet and have to do all of this over.

I passed using five different resources. Full programs, apps, podcasts, practice tests, all of them partly overlapping and none of them telling me what actually mattered. I wanted one thing that would.

So that is what this is.

Start with the free module

No card required. The first module is yours whether or not you buy anything.

It tells you what matters

Most material treats every fact as equally important, which is exhausting and untrue. Every lesson here carries a tag, and the tag is a promise about how hard you should work to keep it.

Forever. You will use this for the rest of your career. Learn it as reasoning rather than recall.

Six weeks, mostly. Real content that fades after the exam, and that is genuinely fine.

Memorize and release. Pure recall, no reasoning underneath. Cram it, use it, forget it without guilt.

It tells you why you were wrong

You commit to an answer before you find out whether it was right. Then every option is explained — including why the one you picked was tempting.

A patient with stage 4 chronic kidney disease asks whether she should switch to a salt substitute. What is your concern?

aSalt substitutes are less effective at reducing sodium intake

bThey are potassium chloride, and a potassium load in stage 4 CKD risks hyperkalemia

cThey have an unpleasant taste that reduces adherence

dNo concern; salt substitutes are recommended for hypertension

b. The general advice to increase potassium does not apply here, and this is the contradiction worth holding.

You chose d. Salt substitutes have trial evidence for cardiovascular benefit at population level — and those trials excluded people with significant kidney disease, which is exactly this patient. Population benefit and individual contraindication arrived together.

Population versus individual

c. Bitterness from potassium chloride is a real adherence issue and not the safety concern.

a. They do reduce sodium intake effectively.

A real question from the hypertension set.

And it tells you what your mistakes have in common

Every wrong answer is tagged with the kind of error it was. Across a few hundred questions, those tags stop being noise and start being a habit with a name.

Outdated knowledge2

A single miss is a gap you can look up. The same error type across four unrelated topics is something else — and it will keep costing you until someone names it.

One price, bought once

Everything: all modules, every question set, the pattern report, and updates as guidelines change. No tiers, no upsells, no subscription.

How long does it take to get through?

That depends entirely on where you are starting and how much time you have. The triage tags exist so you can spend your hours where they matter rather than reading everything at equal depth.

Is it current?

It is written against the current CDR test specifications, and lessons carry a note where a topic is actively changing. Guidelines move, so the course is reviewed and updated rather than written once.

What if I have already failed it once?

Then the pattern report is the part built for you. Knowing you scored poorly tells you very little. Knowing that one kind of reasoning error cost you points across four different topics tells you what to actually do next.

What if it is not what I expected?

Write to [email protected] within fourteen days and I will refund you in full. You do not need to explain why, and there is no form. I would rather you spent the money on something that helps you than kept something that did not.

Do I still need other resources?

Practice tests under timed conditions are worth doing whatever you study with, because pacing is its own skill. This is meant to replace the pile of partly overlapping programs, not the experience of sitting a full-length test.
