Decision matrix

Choose the route that matches the risk.

01

DIY from public guidance

Use this when the issue is low-risk and you have time to read primary sources, build your own checklist, and keep evidence yourself.

02

Run the free diagnostic first

Best first move when you need a fast private screening result before buying anything.

03

Use the paid kit

Best fit when the problem is recurring, evidence-heavy, and specific enough that a buy-once workflow is cheaper than rebuilding from scratch.

04

Hire qualified help

Use this for legal, tax, medical, employment, accessibility, compliance, regulated, disputed or high-value cases where judgement matters.

Reviewed product

What the paid route adds

Included component

Open-book navigation guide

A step-by-step workflow for mapping question topics to parts, chapters, sections, appendices and tables without reproducing regulation text.

Included component

Locator drill

A local browser drill that asks where to look in the book, records timing, and helps candidates practise retrieval rather than memorising answers.

Included component

Printable navigation index and tab worksheet

Editable CSV templates for planning a topic-to-location index and physical tabs, subject to the candidate's provider rules on permitted materials.

Included component

A3 to A4 review worksheet

A confirm-first worksheet for noting topics that may have moved or changed between old study notes and the current A4 copy.
