This audit is for early-career dentists deciding whether Pastest is the right bank for MFDS Part 1, the single-best-answer written examination. The short version: Pastest's dentistry product is a credible, well-established option, but it is a shared bank spanning several dental exams rather than an MFDS-Part-1-specific one, and the vendor does not publish a per-exam or per-part question breakdown. So the principal limitation is coverage transparency — you cannot see, from the headline total, how much of it is genuinely MFDS Part 1.
What Pastest offers for MFDS Part 1 right now
As of 19 July 2026, Pastest markets a single Dentistry subscription said to help with "all major dentistry exams, including Finals, MFDS, MJDF and ORE" (vendor-reported). It advertises 1,000+ questions with 700+ SBA explanations (vendor-reported), a "Tutor mode" described as instant, on-demand AI support while you answer, and analytics that flag weaknesses in real time. Subscriptions are listed at roughly £69.99 for three months, £79.99 for six and £99.99 for twelve (vendor-reported), with a 48-hour free trial. Verify all of this on pastest.com before subscribing.
The critical audit point: because the bank pools multiple exams, the vendor page does not state how many of those 1,000+ questions are mapped specifically to MFDS Part 1 as opposed to MFDS Part 2, MJDF, ORE or undergraduate Finals. Treat "1,000+" as a whole-product figure, not an MFDS Part 1 count, until the vendor publishes the split.
MFDS Part 1: the official shape of the exam
MFDS Part 1 (Membership of the Faculty of Dental Surgery) is a computer-based, single-best-answer written examination testing clinical dental sciences. The Royal College of Surgeons of Edinburgh currently states 180 single-best-answer questions over three hours, delivered online twice a year, usually in April and October (rcsed.ac.uk, checked 19 July 2026). It is offered through more than one college — RCS England, RCS Edinburgh and RCPS Glasgow — so confirm the exact count, duration and regulations with the specific faculty you are entering through, as details can differ. The syllabus spans the clinical dental sciences and the applied basic sciences that underpin them, testing problem-solving, evaluation of evidence, critical reading and management of the whole patient rather than isolated recall.
The medicines reference for dental prescribing content is the SmPC via the electronic medicines compendium (eMC), read alongside SDCEP and NICE guidance — not a formulary shorthand. That distinction matters when you audit whether a bank's drug answers are current and UK-specific.
Record the live count, then break it down by domain
Do not accept the headline total. Build a simple blueprint-coverage matrix: list the MFDS Part 1 domains down the side — oral biology and human disease, oral pathology and medicine, restorative dentistry, periodontology, endodontics, prosthodontics, paediatric dentistry and orthodontics, oral surgery, pharmacology and therapeutics, dental public health and evidence-based practice, law, ethics and professionalism — and, as you work through the bank, tally how many questions you actually meet in each. Within a fortnight you will have a truer picture than any marketing total: which domains are richly served, which are thin, and where the bank is really pitched.
| Audit dimension | What to record | Why it matters for MFDS Part 1 |
|---|---|---|
| Domain volume | Questions actually met per syllabus domain | Reveals thin areas the headline total hides |
| Part specificity | Share clearly mapped to Part 1 vs Part 2/MJDF/ORE | Shared bank inflates the apparent Part 1 count |
| Cognitive level | Recall vs application vs management sequencing | Part 1 rewards applied reasoning, not pure recall |
| Currency | Drug/guideline answers vs SmPC/eMC, SDCEP, NICE | Out-of-date items train the wrong rule |
| Duplication | Near-duplicate stems and repeated concepts | Completion can decay into recognition |
Sample question style: recall versus application
Audit a stratified sample of, say, forty items for cognitive level. For each, note whether it tests simple recall, application to a scenario, or management sequencing; how long and cluttered the stem is; how plausible the distractors are; and whether it uses images or data interpretation. MFDS Part 1 leans toward applied reasoning and management judgement, so a bank weighted heavily to one-line recall items will feel easy and under-prepare you for the real stems. Note in particular whether dental radiographs, clinical photographs and histopathology images appear, because these are hard to revise from text alone.
Jurisdiction and recency
Take a stratified sample across pharmacology, medical emergencies, radiography and governance, and check each answer against current UK primary sources — SDCEP, NICE, the SmPC/eMC and GDC standards — recording the date you checked. Banks that pool exams and markets can carry drifted or dated answers, especially on prescribing, medical emergencies in dental practice, and consent. If more than a small fraction of your sample is out of date or non-UK, factor that into how much you trust the bank's explanations unverified.
Format gap: what a Q-bank cannot do
State it plainly. A single-best-answer bank is well suited to the knowledge and applied-reasoning core of MFDS Part 1, but three things sit at its edge: dental image interpretation (radiographs, clinical and histological images), applied basic science tested through unfamiliar vignettes, and college-specific question style. Pastest's "Tutor mode" AI support can help you interrogate an item, but an AI tutor is not a substitute for verified image banks or the College's own sample material. Do not assume text-based revision alone prepares you for image-heavy items.
Duplication and contamination
The quiet risk in any large bank is that completion becomes recognition. As you approach the end, watch for near-duplicate stems and repeated concepts dressed in new words; when your score climbs mostly because you recognise items rather than reason through them, the number has stopped measuring readiness. That is exactly why a coverage percentage inside a bank you have half-memorised is not your exam score — and why a clean, unseen measurement set matters near the end.
Best-fit matrix: where Pastest fits your run
- Foundation building: Reasonable, given the explanation depth and Tutor-mode support — but confirm domain coverage first.
- First-pass bank: A defensible spine, provided you verify the Part 1 share and set domain floors.
- Second bank: Useful if your first bank is thin in a domain your audit exposed.
- Retake: Strong if your previous failure was knowledge-based and you use the analytics to target weak domains.
- Final simulation: Weaker on its own — you need timed, mixed, unseen material and image practice the shared bank may not fully supply.
Worked example: a seven-day plan
An early-career dentist, seven weeks out, using Pastest to build and iatroX for unseen transfer measurement. No proprietary-algorithm claims.
- Day 1: 40 mixed Pastest items; start the blueprint-coverage matrix and error-tag every miss.
- Day 2: Service your two thinnest domains with topic-filtered practice; use Tutor mode to interrogate, not to be told the answer.
- Day 3: Source reads for day-2 knowledge gaps; verify any drug fact against the SmPC/eMC and SDCEP.
- Day 4: A jurisdiction-and-recency sample across pharmacology, emergencies and governance; log the review date.
- Day 5: A fresh, unseen, timed MFDS Part 1 block in iatroX — no filtering, no assistance — to measure transfer.
- Day 6: Image-focused revision (radiographs, oral pathology) from a verified source, since the bank may under-serve it.
- Day 7: Update the coverage matrix and error tally; set next week's domain floors.
Decision checklist: continue, supplement, switch or stop
- Continue if your coverage matrix is filling and unseen first-attempt accuracy is rising.
- Supplement if the audit exposes a thin domain or weak image coverage — add a targeted second source rather than grinding the same bank.
- Switch if the Part 1 share turns out to be small or the currency check fails repeatedly and cannot be corrected.
- Stop filtered practice in the final fortnight and move to timed, mixed, unseen blocks plus the College's own sample material.
Decide on measurable gaps in coverage, currency and transfer — not on novelty or on sunk subscription cost.
Three coverage mistakes this audit is designed to stop
The first mistake is trusting the headline total. A shared bank advertising a thousand-plus questions can still leave a genuine Part 1 domain — oral medicine, say, or dental public health — with only a handful of items, and you will not notice until the paper itself. The blueprint-coverage matrix exists to surface that gap while there is still time to plug it from another source.
The second mistake is mistaking a rising percentage for rising readiness. Late in any bank, most of your gains come from recognising items you have already seen rather than reasoning through new ones. Ninety per cent on material you have half-memorised tells you very little about a fresh, unseen paper, which is exactly why the measurement set has to stay clean and unseen until near the end.
The third mistake is revising dental images from text. Radiographs, clinical photographs and histopathology reward pattern exposure that prose cannot supply, and a single-best-answer bank — however strong its written explanations — will not build that eye on its own. If your audit shows thin image coverage, treat it as a separate revision job with a verified image source, not as something the bank will quietly cover for you.
Bottom line
Pastest's dentistry bank is a credible, explanation-rich option with useful analytics and a Tutor-mode assist, and it is a reasonable spine for MFDS Part 1 knowledge. But it is a shared, multi-exam product without a published Part 1 split, so audit its coverage against the blueprint yourself, verify currency against UK primary sources, shore up image interpretation separately, and reserve a clean, unseen set to measure transfer. Build on the bank; measure elsewhere.
FAQ
Is Pastest enough for MFDS Part 1 on its own? For the knowledge and applied-reasoning core it can be a strong spine, but "on its own" is risky for three reasons: it is a shared multi-exam bank without a published Part 1 question count, it under-serves image interpretation, and completing any single bank drifts toward recognition. Pair it with the College's own sample material, verified image practice and a clean unseen set, and confirm the current scope on pastest.com.
Which MFDS Part 1 component does Pastest not reproduce well? The image-dependent and applied-basic-science items — radiographs, clinical photographs and histopathology, plus college-specific question style — sit at the edge of what a text-based single-best-answer bank can teach. Tutor-mode AI support helps you interrogate items but does not substitute for a verified image bank or the faculty's own specimen questions.
How many Pastest questions should I complete per day for MFDS Part 1? There is no official figure; reviewed quality beats raw volume. Many candidates manage roughly 30–50 questions a day with full review and error-tagging, which teaches far more than a larger unreviewed block. Prioritise clearing domain floors on your coverage matrix and verifying misses over hitting a daily count, and protect one timed mixed block each week.
When should I stop using Pastest and move to mixed mocks? Once every blueprint domain clears its coverage floor and your unseen first-attempt accuracy is stable, filtered single-topic practice yields little. In the final two to three weeks the binding constraints are pacing across 180 questions in three hours and stamina, so shift to timed, mixed, unseen blocks and the College's own material for calibration.
How should I combine Pastest with iatroX without duplicating practice? Give each bank one job: build and drill on Pastest, and reserve iatroX for fresh, unseen, timed blocks that measure transfer — never re-enter a Pastest item into iatroX or the reverse. That separation, described in the iatroX two-Q-bank rule, keeps your calibration clean: one bank to learn on, one unseen bank to measure on.
