My 14yo DS told me this morning, as he was half out of the front door, that he decided to choose Resistant Materials (don't ask me what it is) rather than Religious Studies as his 3rd GCSE optional subject. Apparently the reason is that he doesn't know who the RE teacher will be next year and he wants to do something that won't require "a lot of studying". He is in a grammar school and has got brains, but he's making a mess of it, bad behaviour and lazyness, getting worse by the week. RS is the only subject where is doing really well, his teacher was very pleased that he wanted to continue with this subject. Am I being unreasonable in insisting that he sticks to RS (his other chosen subjects are Geography and Business Studies)? I am so angry with him that I am almost thinking about taking him out of grammar school and sending him to the local comprehensive, let somebody else who deserves it more have his place.
