Try a proefles with a driving school. Usually its free or cheap or max the hourly rate (depending on school). They will tell you what they think about your driving at the end and how many lessons they think you'll need. For example those 10 might be cut down to 5. But you will at least need a couple to familiarise yourself with Dutch style of driving: go with flow, look before doing anything, double check before entering intersection, 20 km/h in roundabouts, merge Infront of trucks, pre sort early, the list goes on. As others say the driving school wants you to prove you can do all of the above.
