Not really... we finish compulsory education at 16 (end of Yr. 11 and out GCSEs), then we finish College[/Sixth Form] at 18, and Graduate from University [any time from] at 21.

We're not legally adults until 18... which is weird. We can ruin a girl's life at 16, destroy our lungs with tar at 16, run people down at 17 (16 with moped's), and kill off our liver at 18 when we celebrate becoming an adult. Fun fun fun.
