Disclosure: Med Step Guide is published by QBankly, one of the question banks reviewed on this site.
Most study advice assumes a budget. A fair amount of genuinely useful material costs nothing, and some of it is better than paid alternatives. Here is what earns its place.
Official practice questions
The examination’s own publishers release a set of practice questions publicly. This is the most valuable free resource available, and it is under-used because it is short.
Its value is representativeness: it shows you how the real exam phrases things, what its distractors look like, and how much information a vignette gives you before the question. No third-party bank matches that.
Save it for close to your exam date, where it serves as both a check and familiarisation. Spending it in your first fortnight wastes the one resource that genuinely tells you what the real thing looks like.
The official content outline
The examination publishes documents describing what it covers and roughly in what proportion. Almost nobody reads them.
They are worth an hour. Paid resources paraphrase this material, and the paraphrase is sometimes out of date. Reading the source tells you what is actually examinable and where the weight sits, which is directly useful for deciding what to skip.
Open content material
There is a large amount of high-quality free teaching material covering foundational science, university lecture material, open textbooks, and video explanations of specific mechanisms.
For understanding a concept you are stuck on, this is often better than a paid resource, because you can pick the explanation that suits how you think rather than the one that came bundled.
Where it falls down is coverage and sequencing. It is a set of explanations rather than a course, so you have to bring the structure yourself.
Free trials, used deliberately
Most paid banks offer trials. Used properly, on a topic you already know, to judge explanation quality. They are a legitimate way to choose between them rather than a way to accumulate free questions.
Trying to assemble a preparation out of trials is a false economy: you lose all continuity of analytics and end up with fragments in five interfaces.
What free material does not cover well
A large, well-explained question bank with usable analytics. This is the genuine gap, and it is the part that matters most, because question practice with proper review is the core activity.
Free question sources exist, but explanation quality is inconsistent and the analytics are usually absent. Since the explanation is the teaching material, that inconsistency is the whole problem rather than a minor one.
An honest summary
You can cover the content for free. You cannot easily replicate a good question bank for free.
If money is tight, that is where to spend it, and it is worth prioritising over additional content resources, which are the part free material handles best.
When you do spend, judge on explanations rather than on the size of the bank. QBankly is one of the cheaper ways to get a full set with detailed explanations, and it has a free trial to test that claim on.
Building a free-first plan
If cost is the binding constraint, the sequence that works is: learn content from open material, structure it against the official content outline, and spend whatever budget you have on a single question bank with good explanations.
That inverts the usual pattern, where students buy a content resource first and treat questions as the thing they will get to. The content is the part free material covers well; questions with proper explanations are the part it does not.
Judging free question sources
Some free question sets are genuinely useful and some are actively misleading, outdated answers, explanations that restate the key, or questions written in a style the exam does not use.
Apply the same test as for a paid bank. Do the explanations teach? Are they self-contained? If a free source fails that test, it is not a cheaper version of a good bank; it is practice at answering questions badly.
What to avoid
Assembling preparation from a dozen fragmentary free sources. The lack of continuity costs you any usable picture of your own progress, and the time spent finding and evaluating material is time not spent studying.
Two or three good sources used consistently beats ten sampled.
Frequently asked questions
Can I prepare using only free resources?
It is possible and it is harder. The gap is not content, free content is plentiful, but a large, well-explained question bank, which is the part free options cover least well.
What is the single most valuable free resource?
The official practice questions released by the examination's publishers. They are the best available guide to how the real exam phrases things, and they are worth saving for close to your exam date.
