A candidate already holds Category A and now sits theory for Category B. How does Ordinance No. 38 treat that upgrade paper compared with a first-time B sitting?

1. The upgrade paper is 25 questions with a 55-point maximum and a 50-point pass, and it is not the first-time B format
2. The upgrade candidate skips theory entirely and takes only the practical test
3. The upgrade paper is 39 questions scored like a motorcycle sitting
4. The upgrade paper is still 45 questions, 97 points and 40 minutes, identical to first-time B
