The 80/20 of score gain
Candidates who plateau in the final weeks almost always do the same thing: they practise the questions that feel comfortable and skip the ones that don't. The result is 2-3 weeks of hard work that barely moves the dial.
The biggest score gain comes from the opposite habit — repeatedly returning to the questions where you've already shown weakness. A weakness mock automates that habit. Instead of you having to remember which questions you got wrong three weeks ago, the system pulls them back into your next mock at the right time.
How the weakness mock is built
- 1The system reads every question you've attempted, along with whether you got it right, when you last saw it, and how confident you were.
- 2Each question is sorted into one of five buckets: due for review (per the SRS schedule), previously wrong, almost due, never attempted, and mastered.
- 3When you generate a mock, questions are pulled in priority order — wrongs and due-for-review come first, almost-due next, with new questions filling any remaining slots.
- 4The mock saves a selection breakdown so you can see exactly how many questions came from each bucket. No hidden weighting, no proprietary score.
- 5When you re-attempt a question and get it right, the SRS schedule pushes it further into the future. Get it wrong, and it comes back sooner.
Why question-level rather than topic-level?
Topic-level scheduling sounds clean but it averages over questions of very different difficulty. Item-level SRS — applied to each question individually — picks up the precise items you struggled with, not just the broad subject. It is also the same principle that powers our Flashcards feature, applied to the question bank.
What this feature is and isn't
This is not a black-box 'AI coach'. The weakness mock is a transparent, deterministic algorithm: it looks at your submission history, applies a published spaced-repetition rule, and pulls the questions in a fixed priority order. There is no hidden score and no proprietary weighting.
- Deterministic — same inputs give the same output every time
- Transparent — every mock surfaces the exact selection breakdown
- Scoped — works at the question level, not the topic level (the dashboard shows your topic-level weak spots separately)
Frequently asked questions
How many attempts do I need before a weakness mock is useful?+
Realistically, 30-50 attempts. Below that threshold the question pool tagged as 'previously wrong' or 'due for review' is very small, so the mock will be padded with new questions. The more you attempt, the more the mock leans into your weak spots.
Can I choose which topic the weakness mock pulls from?+
Yes. By default the mock pulls from across the whole bank, but you can restrict it to a single topic from the Smart Tools panel. Multi-topic targeting is on the roadmap.
Does the weakness mock count toward my readiness score?+
Yes. Every attempt — whether on a weakness mock, a timed mock, or a freeform practice block — contributes to your rolling accuracy and your dashboard metrics.
Is this the same as flashcard spaced repetition?+
It uses the same spaced-repetition principle but applied to multiple-choice questions rather than flashcards. Wrong or due-for-review questions surface again sooner; correct answers push the question further into the future. Our Flashcards feature applies the same logic at the card level for fact recall.
