from the age of 13 ( i am currently 14 ) you can drive a 100cc scooter
You can ride a 50cc scooter (not 100cc) from the age of 13 as long as you have got permission from your school:
pl.wikipedia.org/wiki/Karta_motorowerowa
Given that you don't go to school in Poland I don't see how you would be able to get a "karta motorowerowa" so I think that you are going to be stuck until you are 16 and can do your licence in the UK. Unless anybody here knows a way around this....?
