Pull your socks up?🤔 What does that mean?

It sounds pretty good. The pronunciation of 'truant' was a little off...you can listen to the Google auto pronunciation, these are generally very accurate for English. 'To play truant' I've never really heard as an expression, in the US, the saying used to be 'to play hooky,' i.e. to slip class. 'Truant' is usually a more legalistic/official word that describes skipping school. Not sure about the UK. The 'has your' in 'has your teacher' was also a little accent heavy, again, the Google lady will sort you out.
