Most advice about choosing a question bank is written for students at US medical schools, where a course is covering the same material in parallel and the study period is a defined block of weeks.
If neither of those is true for you, some of the selection criteria change.
Explanation depth matters more
A US student who does not understand an explanation can fall back on the lecture that covered it last month. If you are working through material your own curriculum framed differently, or has not reached, the explanation is often all you have.
That makes explanation quality the dominant criterion rather than one among several. Judge it directly: take a trial, find questions in an area you know well, and read the explanations critically. Do they teach the concept, or do they justify the answer key?
A bank with terse explanations is much more expensive for you than for a student with a parallel course, whatever the subscription costs.
Conventions and self-containedness
Check how the bank handles reference ranges, units and drug naming. Some present them the way the exam does; some assume you have absorbed the conventions already.
Related: check whether explanations assume familiarity with a particular US textbook or lecture series. Some do, and following those references is expensive if you do not have the source.
Subscription length over headline price
A US dedicated period is a defined block. Timelines outside that pattern are often longer and less predictable, fitted around a degree, around clinical duties, or around exam centre availability.
That makes the length of access more important than the sticker price. A cheaper subscription that expires before you finish is not cheaper, and extending late is usually the worst-value way to buy access.
Work out honestly how long you need, add margin for the parts of your schedule you do not control, and choose on that basis.
Practical access
Payment methods, regional pricing where offered, and whether the platform performs acceptably on a slower connection are all real constraints that get no attention in advice written for a different context.
Check them before committing rather than after. A resource you cannot reliably load during your study hours is not a resource.
How to actually decide
Trials exist. Use two or three of them on the same topic, one you know well, so you can judge the explanations rather than be impressed by unfamiliar content.
Ask three questions. Do the explanations teach me something I did not know? Are they self-contained, or do they assume a resource I do not have? Will the access period cover my realistic timeline?
Worth including in that comparison is QBankly, which competes on explanation depth rather than on question count and does not assume a separate reference library.
Then pick one and finish it. The most common expensive mistake in this area is buying two banks, completing neither, and concluding that the problem was the choice of bank.
Testing a trial properly from outside the US
Do the trial at the time of day you actually study, on the connection you actually have. A platform that performs well on a fast connection during a quiet afternoon may behave differently at the hours you can realistically work.
Then do twenty questions in a system you know well and read every explanation critically. You are assessing the teaching, not the content, and using familiar material is the only way to separate the two.
Budgeting across a longer timeline
Preparation fitted around a foreign curriculum often runs longer than a US dedicated period, and access periods are priced for the shorter pattern.
Work out your realistic timeline including the parts you do not control, exam centre availability, curriculum demands, then buy access that covers it with margin. Extending late is consistently the worst-value way to buy time.
One bank, finished
The advice that matters most is the same as anywhere: finish one. The temptation to buy a second when progress feels slow is strong, and it resets your analytics while leaving the underlying problem, usually insufficient review, untouched.
A single bank completed with thorough review is worth more than two sampled, and the gap is not close.
Frequently asked questions
Do I need a different question bank as an IMG?
Not a different one, but possibly different selection criteria. Explanation depth and self-containedness matter more when there is no parallel course covering the same material.
Is one bank enough?
For most students yes, and finishing one thoroughly beats sampling two. A second is worth considering only if you complete the first with time to spare.
