Bonsoir,
Hi !
I've just received you email. You shouldn't be so nervous about it. I'm sure your dad is going to understand if you explain him how difficult the test was. But as you're my friend, I advise you to be more serious. You shouldn't spend so much time on videogames. You should study. Don't hesitate to ask me, I can help you . Phhysics is my favourite subject at school.
You should be honest with your dad, and promise him to do your best to improve your results.
I'm sure he'll believe you.
Good luck !
