What a mock score
can and cannot tell you
The Becker Bump is the idea that your real exam score arrives some number of points above your practice score. Whether that gap exists for you is not something anyone outside the vendor can audit: the comparison is internal, and nobody publishes which students it held for. The forum spreadsheets trying to pin down its size cannot settle it either — they are samples of people who chose to post. This page is about the question underneath, which you can check: not how many points to add, but how much evidence you have and how uncertain it is.
Why the crowd-sourced tables cannot answer it
Search this topic and the first results are a spreadsheet thread and a forum asking people to post their practice score next to their reported score. That is a reasonable instinct and it produces a number that cannot mean what people want it to mean, for three reasons that compound:
- The sample selects itself. A candidate who gained fifteen points has a reason to post. A candidate who scored the same or lower mostly does not. The average of what gets posted is therefore not the average of what happens.
- There is no denominator. Nobody knows how many people took the same practice exam and never appeared in the thread, so there is no population to generalise to.
- “Mock score” is not one thing. Which practice exam, taken when in preparation, under time or not, after how much review — these are not controlled between posts, and each of them moves the number more than the effect being measured.
None of that makes the posters wrong to wonder. It makes the specific quantity they are chasing unavailable from where they are standing.
A points offset is the wrong shape of answer
Suppose the number existed and was known. It would still be an average, and an average offset applied to your score tells you nothing about whether your preparation is thin in a specific place. Two candidates with the same practice score can be in completely different positions: one has answered several hundred questions across every content area, the other has answered a few dozen concentrated in the material they already knew.
A single number cannot carry that difference, which is why adding points to it does not help. The two things that do carry it are how much you have tested yourself and how uncertain the resulting estimate is — and a practice score reports neither.
The question you can actually check
Replace “what will my real score be” with two questions you can answer today, with numbers you already have:
- How much evidence is behind my sense of readiness? Count questions you answered under time, not pages you read. Untested is not the same as weak, but it is also not the same as tested.
- How much would that estimate move if a few questions had gone differently? If the answer is “a lot”, the estimate is thin regardless of how comfortable the number looks.
Our pass-probability estimator is built to answer exactly those two: it starts from the published FAR pass rate and moves in proportion to the evidence you enter, and it shows the evidence count and the uncertainty band next to the figure. The full method, including what it cannot do →
To be explicit about our own position: nothing on this site has been validated against exam outcomes — not one figure, including that estimate. The argument on this page is about which question is answerable, not a claim that our number is closer to the truth than anyone else’s.
If you are deciding whether to sit
That decision is where this actually bites, because it costs money each time. The inputs worth having are the base rate, your own evidence, and an honest read of pacing — not a points adjustment.
Common questions
Is the Becker Bump real?
From outside, the size of it is not an answerable question. It describes a gap between a vendor’s own practice scores and reported exam scores, and no one outside that vendor can audit the comparison or say which students it held for. What you can check is something different and more useful: how much evidence you have, and how uncertain it is.
Why can’t the crowd-sourced spreadsheets settle it?
Because they are samples of people who chose to post. Candidates who gained points have a reason to share and candidates who did not mostly do not, so the average of a self-selected thread cannot estimate a population offset. There is also no shared definition of which practice exam counts, taken under what conditions, at what point in preparation.
So should I ignore my mock scores?
No — use them as evidence rather than as a forecast. A practice score tells you something about coverage on the questions you actually answered. It becomes misleading the moment it is treated as a number to add points to.
What should I be asking instead?
Two things a single score cannot express. How much have I actually tested myself, under time, rather than read? And how wide is the uncertainty around that — would a handful of different questions have moved the number a lot? A readiness estimate that does not show you both is a point estimate pretending to be a measurement.
Has your own estimate been checked against real exam results?
No. Nothing on this site has been validated against exam outcomes — not one figure. Our estimator starts at the published FAR pass rate and moves in proportion to the evidence you give it, and it shows you the evidence count and the uncertainty band alongside the number. That is a difference in method, not a claim that our number is closer to the truth.
What we are building for this
Exam Copilot is FAR practice, diagnosis and tutoring built around an evidence-based estimate rather than around a content library. When you miss a question, it opens by asking you one thing about the specific wrong choice you made, rather than pasting the explanation. You get the full walkthrough within a few exchanges either way — and if you would rather just have it, ask three times and it is yours.
It is not open yet — no question in the practice bank has been reviewed by a licensed CPA.
