no you don't DUO you only have to have updated the chart with the new data.
If you want a paper one you just get the Jepp paper VFR ones which are poo but do the job.
Yes the school shop will say that you need to most current ones because they want you to buy them otherwise they are down out of date charts which you can't send back. There are even folk out there that will tell you that its illegal to hack off the bits you don't use and have a cut down local area chart. Some rubbish about the legend needs to be in tacked.
All a complete and utter load of poo.
