play hooky, play truant, play the wag, bunning off school,to skip school,cut classes

Dear teachers,

Would you be kind enough to tell me your opinion concerning the following sentences and especially the usage of the expresses in bold?

I skipped school today because there was a boring school assembly.
Instead of going to school today I played hooky.

Would you tell me whether I might use also the following expressions: truant (play truant), cut classes, to skip school, to wag school (to play the wag), to ditch school, bunning off school.

Who should I keep an eye on, the little old lady over there or this group of kids bunning off school?
Young people who truant regularly are less likely to do well at GCSE.

Thank you for your efforts.

Regards,

V.

In AmE, the traditional phrase is either "skipped school" or "ditched school" when one plays hooky. (By the way, playing hooky was once the common expression, but that died out circa 1960.) "Truant" is more of an official term, used by police or school officials when they make notations on that dreaded "permanent record" you always hear about when you're a student. :-)
