Arwel is now 19 years old and has some speech due to the help he received at his previous school, though there was little or no provision for post-19 education.
Mae Arwel bellach yn 19 oed ac mae ganddo rywfaint o leferydd diolch i gymorth a gafodd yn ei ysgol flaenorol, er nad oedd llawer neu ddim darpariaeth ar gyfer addysg ôl-19.
