Why mocks matter more than another reading pass
CFA Institute's long-standing guidance is roughly 300 hours of study per level. By the time you have worked through the curriculum, the limiting factor is rarely how much you have read — it is recall under time pressure and exam stamina. Mock exams test both, and they show which topics are costing you marks.
When to start
- From week one: topic-wise practice questions after each reading, not just at the end
- Full-length mocks: start once you have covered most of the curriculum, typically the last four to six weeks
- Save your best mocks: keep at least one or two official or high-quality mocks unseen until the final fortnight, so they work as a realistic gauge
CFA Institute provides official mock exams to registered candidates; check your candidate portal for what is available for your level and exam window.
How many mocks are enough?
There is no magic number. A practical target for most working candidates is three to five full mocks, spaced about a week apart, each followed by a thorough review. Two mocks reviewed properly beat five rushed through — the learning happens in the review, not the attempt.
Simulate the real day
- Sit at the same time of day as your exam slot, with the break structure your level uses
- Use only what the exam allows — the permitted calculator and no notes
- Practise the format of your own level: Level I is multiple-choice, Level II is built on item sets (vignettes), and Level III combines constructed-response questions with item sets
- Do not pause, search or check answers mid-mock
A review method that works: the error log
For every question you got wrong or guessed, log why. After two or three mocks the pattern usually tells you exactly what to fix.
| Error type | What happened | Fix |
|---|---|---|
| Knowledge gap | You did not know the concept or formula | Re-learn the reading, then do five fresh questions on it |
| Application error | You knew it but applied it wrongly | Write the step you skipped; redo the question cold after a day |
| Reading or time error | You misread the stem or ran out of time | Practise underlining the ask; set a per-question time budget |
| Lucky guess | Right answer, wrong or no reasoning | Treat it as wrong and review the logic |
An example final-month schedule
| Week | Focus |
|---|---|
| Week 1 | Topic drills on weak areas, mock 1, full error-log review |
| Week 2 | Re-learn the top error-log topics, mock 2 |
| Week 3 | Mock 3, formula sheet and ethics refresh |
| Week 4 | Light revision, one timed section, rest before exam day |

Frequently Asked Questions
How many CFA mock exams should I take?
Most working candidates do well with three to five full-length mocks, about a week apart, each followed by a detailed review. Quality of review matters more than the count.
When should I start full-length mocks?
Once you have covered most of the curriculum — typically the last four to six weeks. Use topic-wise questions from the start.
Should I trust my mock score as a prediction?
Treat it as a trend and a topic-level diagnostic rather than a prediction. Conditions, question style and your stamina on the day all differ.
What do I do with wrong answers?
Log each one by type — knowledge gap, application error, reading or time error, or lucky guess — and fix the most frequent type first.
