Amir has just received his provisional HGV entitlement and wants to book Driver CPC part 2 before taking part 1. What should he do?

1. Book part 2 now, because GOV.UK allows it once he has the correct provisional licence
2. Wait until he has passed both part 1a and part 1b
3. Take part 4 first, then book part 2
4. Book only by phone because all new HGV candidates are barred from online booking
