If you know someone who will be sitting exams soon (SATs, GCSEs, A/AS Levels, University Finals - any academic exams!) why don't you send them a card to encourage them and remind them that God cares about every detail of our lives?
If you can't send this card to someone you know who is preparing to sit exams then why not send them this blog post just to let them know that they are in your thoughts?
Write something about yourself. No need to be fancy, just an overview.
