Switching question banks is sometimes the right move and is often a mistake. Most candidates who switch do so because their review quality was poor, not because the platform was — and a new bank simply resets the same recognition problem on unfamiliar material. Before you spend money or restart, work out which situation you are actually in.
When not to switch
Stay where you are if any of these is true: you completed less than half to 60% of your current bank; you are not reviewing your misses properly; you have no error log; you only ever practise untimed; or you have never mapped your weak topics. In every one of these cases the limiting factor is your method, and a new bank will not change it. Finishing your current bank with a proper review loop attached will almost always beat starting a fresh one.
When switching or adding makes sense
Consider adding or changing resources if you have genuinely memorised your current bank, if its explanations no longer resolve your misconceptions, if the bank is outdated, if its style diverges from the current exam, or if you need something specific it cannot offer — free-entry calculations, more image and data questions, or guideline-grounded reasoning.
Choosing by category, not brand
It helps to think in categories rather than tribally:
| Need | Reasonable options |
|---|---|
| Breadth and volume | PassMedicine, PLABable, UWorld |
| Harder, polished UK banks | Quesmed, Pastest |
| Pharmacy-specific | OnTrack |
| Adaptive diagnosis and tutor layer | iatroX |
These are not competitors so much as different jobs. A volume bank builds coverage; a harder bank stretches reasoning; an adaptive layer finds and repairs the specific weaknesses the others leave behind.
Where iatroX fits
The honest framing iatroX takes is that PassMedicine, Pastest, Quesmed, PLABable, UWorld and OnTrack can all be useful, and the mistake is rarely the platform — it is doing questions without a diagnostic review loop. iatroX adds the adaptive sequencing, performance dashboard and Socratic Tutor that turn mistakes into a targeted plan, and its UK core banks are free, so running a diagnostic before you buy another resource costs nothing. If the diagnostic shows a coverage gap, finish your current bank; if it shows a review-quality or pacing problem, fix the loop. Either way, you will have spent the decision wisely.
A short FAQ
Is it ever right to switch mid-revision? Yes, if you have genuinely exhausted your bank or it no longer resolves your misconceptions — but not as a reaction to a single bad mock.
What should I do before buying anything? Run a free diagnostic to establish whether your problem is coverage or review quality. The answer determines whether a new bank would help at all.
Can adding a second bank backfire? It can, if it splits your attention and you end up reviewing neither properly. One bank reviewed well beats two reviewed poorly.
