+- `actionable`: If the student did not use `ofPattern` and `parse` methods in the `schedule` method, instruct the student to do so.
+- `actionable`: If the student did not use `isBefore` or `compareTo` methods in the `hasPassed` method, instruct the student to do so.
+- `actionable`: If the student did not use `getHour` in the `isAfternoonAppointment` method, instruct the student to do so.
+- `actionable`: If the student did not use `ofPattern` and `DateTimeFormatter.format` methods in the `getDescription` method, instruct the student to do so.
+- `actionable`: If the student did not use `getYear` in the `getAnniversaryDate` method, instruct the student to do so.
+- `informative`: If the solution uses `String.format` in the `getDescription` method, inform the student that this cause a small performance penalty compared to string concatenation.
+
+If the solution does not receive any of the above feedback, it must be exemplar.
+Leave a `celebratory` comment to celebrate the success!
