If you pass the Rules of the Road part online but fail the Road Sign Recognition part, what does Nova Scotia's current Class 7 page say about retesting?

1. Pay for another test and retake only the Road Sign Recognition part, with no online waiting period
2. Retake both parts after a mandatory 30-day wait
3. Retake only the Rules part because that is the main test
4. Schedule a road test instead of retaking the sign part
