The most useful note is the one that helps you make a different decision next time.
Record the cause, not just the answer
An error log becomes difficult to use when every entry is a pasted explanation. Begin with what changed the answer: a fact you did not know, a detail you misread, a task you misunderstood or a distinction you could not explain.
Your label can be simple. The point is to separate the kinds of work required. An uncertain mechanism needs a different response from a rushed reading habit. A question may involve more than one cause; write only what helps you decide what to work on.
Keep the entry small enough to revisit
Use your personal question note for a short observation and, where useful, bookmark the question. A note such as “explain why this alternative does not fit the final clue” is easier to act on than a page of copied material.
After permitted result review, add the explanation in your own words. If you cannot explain the distinction yet, leave a precise question for your tutor. The note should not claim certainty that you do not have.
Look across several attempts
Review the notes from a few sessions together. Which uncertainty keeps returning? Which topic appears repeatedly? Avoid choosing your next session solely because a single small breakdown has a low percentage.
Connect your error-log observations with the subject and system results released in your dashboard. The combination can suggest a useful focus: a topic to rebuild, a comparison to practice or a reading habit to test in a mixed session.
Give the next session a specific purpose
Choose one recurring issue and describe how you will address it. That might mean reviewing a mechanism before fresh questions, practicing a distinction or deliberately stating the question’s task before reading the options.
Return to the note afterwards. Did the new session reveal the same gap, or a different one? Your log should evolve as your preparation changes. Bring unresolved patterns to your tutor with concrete examples from the work you have completed.
