A useful CFA practice error log records the gap that caused a wrong answer and the next action that will test whether you have fixed it. Write the topic, the error type, the corrected reasoning and a fresh retry date. At the end of each week, group repeated errors and give the next practice block to the pattern that still survives a fresh question.
Record the cause, not a copy of the question
CFA Institute says its practice questions provide feedback and explanations. Read that explanation after you have committed to an answer, then write a short diagnosis in your own words. The log should let you reconstruct the thinking error without storing the question stem or answer choices. That also keeps the sheet useful when a different question tests the same skill.
| Topic and objective | The reading or learning objective you were trying to apply. |
| Error type | Concept gap, wrong method, unit or sign slip, misread condition, or timing. |
| Reasoning gap | The specific step you took and why it failed. |
| Correction | The rule or method you can explain without looking at the answer. |
| Retry | A date and a fresh question or small prompt that tests the same step. |
| Result | Whether the retry worked unaided; if not, what remains unclear. |
A row such as “fixed income: treated a yield change in percentage points as a whole number; convert to decimal before estimating price sensitivity” is more useful than “duration wrong”. It points to a repair and a check. If the explanation itself is unclear, mark the row as unresolved rather than copying a solution you cannot yet reproduce.
Use the log at the end of each week
- Scan the rows from the week and group them by the reason for error, not merely by broad syllabus topic. A repeated unit mistake across several readings is one pattern.
- Choose the recurring or unresolved pattern for the next focused practice block. Revisit the relevant lesson only far enough to repair the missing step.
- Try a fresh question without notes. Explain why the correct method applies before checking the answer. Record the new result on the original row.
- Keep a row active if you can solve only the remembered example. Close it when you can handle a new version unaided and explain the method.
Suppose an illustrative week contains errors in bond duration, currency returns and ratio analysis. The topics differ, but the log shows the same unit-conversion error in each. The next block should test units across those topics, rather than reread all three chapters. If the fresh attempts expose a separate conceptual gap, create a separate row for it.
Keep the sheet short enough to use
The log is a decision aid, not a second set of notes. Use plain categories and one line of corrected reasoning. Where a row is only a careless misread, name the missed condition and add a check you can make while practising. Where you guessed correctly but cannot explain why, log it as an uncertain answer rather than treating it as secure knowledge.
CFA Institute’s candidate resources page lists the curriculum, practice questions and study planner together. Use those tools to locate a lesson and arrange the next retry; the weekly priorities should still come from the errors you actually made. The CFA programme page gives the broader exam context, while Omni’s methodology offers a place to fit these focused reviews into a routine.
