Hi, french is my first language! Everything in your text is good, but I would change "chœurs" for "corvée" maybe... and when you say "la cuisine" that means 'the kitchen" if you want to say "cooking" you should probably use the word " cuisiner" which is the verb... and if you want to say "dusting", "époussetage" would maybe be a better word than "Dépoussiérer".... and for "study" I would suggest the word "bureau" if you mean "of his office " and not "of his studies (meaning homework)" because "étudie" means study like analyze.... hope this helps...
