A useful free PSA preparation route needs both assessment familiarisation and prescribing-related question practice. Neither substitutes for the other. The official environment helps candidates understand how tasks are presented; independent resources can supply additional opportunities to interpret information and check their reasoning.
This comparison is published by iatroX, which offers a free PSA bank and is included below. Product descriptions were checked on 19 September 2026. No clinical doses or patient-specific prescribing instructions are provided in this article.
Start with the assessment, not the largest bank
Use the Prescribing Safety Assessment website for the current candidate information and preparation arrangements available to you. Your medical school may also provide access or instructions. Check those before buying an independent package.
The distinction matters because an external bank may teach a relevant skill without reproducing every aspect of the official task or interface. Familiarity with one website should not be mistaken for familiarity with the examination environment.
BMJ OnExamination's PSA product is a paid preparation option to inspect for additional practice and explanation. Its commercial price and access period should be checked at purchase. The question is not whether a paid product is inherently better, but whether it supplies something your existing preparation lacks.
Four different kinds of error need different practice
A learner can misunderstand the clinical problem, misread the task, mishandle a calculation or fail to check the plausibility of the result. Recording only "prescribing error" makes those causes difficult to distinguish.
For a fictional educational example, imagine a question that asks the candidate to identify the most relevant missing information before making a decision. A learner jumps directly to a familiar treatment choice. The problem is not necessarily lack of pharmacological knowledge; it may be failure to answer the actual question.
Another learner may understand the decision but repeatedly mishandle units in an abstract calculation. They need a systematic checking method and suitable calculation practice, not another broad summary of the condition. No drug quantities are needed to demonstrate that distinction.
What a free bank can reasonably do
According to iatroX's September 2026 product information, its PSA bank is genuinely free rather than a small sample with an expiry. It can therefore serve as an ongoing source of supplementary practice. That is different from the limited free samples available for many paid examination banks.
The iatroX examination catalogue is the appropriate place to select the assessment. Use the bank to identify a pattern of mistakes, then return to the relevant authoritative learning material. A free resource still requires critical appraisal: inspect the explanation and check a disputed point rather than treating the absence of a price as either a guarantee or a warning sign.
Give each resource a defined job
A practical preparation route might assign official materials to task familiarisation, a question bank to repeated practice and appropriate teaching to a persistent conceptual gap. That is a proposed study arrangement, not a validated programme or a claim about pass probability.
Keep an error record with the requested task, the reason for the mistake and the checking step you will use next time. Avoid copying long answer paragraphs without extracting a usable correction. On a later attempt, test the same underlying skill through a different example.
If a sample demonstrates a format that your free resources do not cover adequately, a paid product may be worthwhile. If the existing resources already support effective practice, there is no obligation to purchase another subscription simply because the examination is approaching.
A verdict that preserves the free option
Use the official preparation route first for assessment-specific instructions. Use iatroX's free PSA questions when they meet the need for additional practice. Consider BMJ or another paid resource when its content, task coverage or explanations provide a clear additional benefit. Ongoing tutoring may be useful for repeated reasoning errors, but it should not be presented as a requirement for accessing the free bank.
Try the relevant learning experience
The relevant iatroX proposition is not access to unrelated examinations. It is using questions, targeted Tutor follow-up and an exam-date-aware study planner for PSA. Per the September 2026 product brief, the planner takes daily available study time and quiz performance into account.
The PSA bank is genuinely free under the September 2026 offer, not an expiring twenty-question trial. Ongoing tutoring is paid; a separate complete introductory Tutor session is available through a free account.
At the UK prices published on 19 September 2026, annual access costs £99 upfront, equivalent to £8.25 per month billed annually; monthly access costs £29. The paid package includes questions, Tutor, planning, simulations and CPD tools. Value depends on using several relevant learning methods, not on collecting access to unrelated exams.
Frequently asked questions
Is the iatroX PSA bank an expiring trial?
No. The September 2026 product offer describes it as a genuinely free bank, while ongoing Socratic tutoring is paid.
Can an independent bank replace official PSA preparation?
No. Use official materials and your institution's instructions for the assessment arrangements and interface.
When should I pay for another PSA resource?
When its specific task coverage, teaching or explanations address a demonstrated gap that your existing access does not resolve.
