Every UK GP knows the update-course rhythm: once or twice a year, a day with NB Medical's Hot Topics or Red Whale's GP Update, a folder of gold, a fortnight of good intentions, and then the slow leak until the next course. iatroX enters that picture not as a third course but as the answer to the leak. Here is how the three actually relate, and why the strongest setup uses the courses and the continuous layer together.
The update-course model, done by its two masters
NB Medical's Hot Topics and Red Whale's GP Update are the two dominant expressions of the same excellent idea: expert teams read everything, current evidence, guideline change, the medico-legal weather, and compress a year of primary care into an intensive day, live or on demand, backed by reference materials GPs genuinely keep using: NB's concise summaries and companion self-test MCQs, Red Whale's handbook and its distilled pearls. Both produce course certificates plus the substantial reflective material a day of concentrated updating generates; both price per course or subscription, with practice and group options, and current rates are best checked on their sites. Choosing between them is largely a matter of teaching style and calendar; GPs argue the toss affectionately, and neither choice is wrong.
The model's built-in limitation
The limitation is not quality but physics: a periodic download decays. Memory research is unambiguous that massed learning, however brilliant, erodes without retrieval, and a course is the definition of massed learning. Six months on, the attended day survives as a general sense of currency plus whatever the handbook rescues at the point of care. The courses know this, which is why both ship self-test materials; the missing piece is scheduling, something that makes retrieval happen repeatedly, automatically, across the year, tuned to what you personally are losing.
What the continuous layer looks like
That is iatroX's role in this trio: an adaptive question bank across the GP scope, spaced repetition scheduling returns as forgetting approaches, the Socratic Tutor interrogating every miss against guidance cited into NICE, CKS, SIGN and SmPC sources, askiatroX answering the working day's questions with the same citations, and My CPD converting each session into an assessed, appraisal-ready record. Free tier for askiatroX and selected full banks; £29 monthly or £99 annually for the complete platform (last checked August 2026). It teaches no annual day and compresses no literature; it keeps what the courses installed from leaking, and documents the keeping.
Reference materials and AI features, compared
At the point of care, Red Whale's handbook and NB's summaries remain superb curated references, and askiatroX offers the complementary reflex: a natural-language answer with the citation trail into the underlying national guidance when you need the exact current threshold rather than the compressed teaching point. On AI more broadly, the courses' ecosystems are content-first with self-testing attached, while iatroX is assessment-first with tutoring attached; the Tutor's misconception-hunting on missed questions is the piece with no equivalent in the course model.
Cost, time and evidence across a year
A representative year: one update course, its certificate and a page of reflection; plus the continuous layer, perhaps two short question sessions a week, generating a dozen assessed records showing gaps found, corrected and held. Total time beyond the course day: well under an hour a week. Total evidence: the credible participation certificate every portfolio expects, and the assessed learning trail almost none contain. Total cost: the course fee plus £99, which is less than a second course and buys what a second course cannot, namely retention with receipts.
The combined workflow
Attend the course, and within the fortnight run themed question sets across its biggest topics: the scores show what actually lodged. Let the Tutor repair the rest, and spaced repetition carry the repairs across the year. When the bank keeps flagging a domain, that is next year's course-day priority arriving early. File one CPD entry per cycle: course, assessment, correction, re-test. The courses provide the download; the layer provides the persistence; the portfolio finally shows both.
Frequently asked questions
NB Medical or Red Whale, if I can only fund one?
Flip a well-informed coin: both compress the year expertly, and the real differences are teaching style, materials format and which dates fit your diary. Alternating years is a respectable answer that many GPs quietly use, and whichever you pick, the leak problem, and its fix, are identical.
Do the courses' own MCQs make the continuous layer redundant?
They are good self-checks on the course material, and that is their scope: course-anchored, unscheduled, and silent once the season passes. The continuous layer's value is precisely what they lack, adaptive selection across your whole scope and spaced re-testing across the whole year.
When in the year should the course sit?
Wherever your energy is, honestly; the system above makes timing matter less, because the layer maintains whichever month's download you took. If pressed: spring courses pair neatly with an appraisal-year evidence trail that builds through autumn.
