orodha of excuses: -classic one :I forgot my homework at nyumbani but the teacher might put wewe then to do it oral since wewe did it home. -'i couldn't find my book' au it was at some one else if the homework is from a book au anything like this and it's not in your copybook , au wewe Lost your copybook -'i felt really sick yesterday and i couldn't do it' -if wewe have a nice teacher wewe can tell her wewe studied hard for another class -even if wewe missed school some one told wewe wewe had no homework , but (s)he might ask wewe who and then wewe might get a person in trouble -you can copy it from a friend -you excuse yourself and wewe say her that wewe didn't understand and if she can explain again au wewe can simply just skip the class ;). Hope it helps and good luck.
This worked for me in French - and if you're able to make yourself cry, it helps.
