Dear Mrs XXXXXXXX
I am writing to inform you that XXXXX will be absent from school on either Thursday 20th or Friday 21st April to take her LAMDA exam in the Speaking of Verse & Prose. As the nearest public examination centre is in Manchester, it will require a whole day due to the travelling.
I have requested that her exam take place on the Thursday. However LAMDA do not guarantee any such requests and I will not find out the exact date and time until approximately 10 days beforehand. I will let you know the exact date as soon as I have it.
Or should I wait until I have the actual exam date, 10 days before.
