QUESTION:
What are the circles and check-marks next to Memos?
ANSWER:
When you perform a scheduled review, AIVault records each PASS and FAIL, showing the history alongside the displayed Memo. As you might guess, circles are for FAIL and check-marks are for PASS.
NOTE: Browsing Memos does not affect the PASS/FAIL record, even if answers are typed into the input box .
