My daughter is in year 5. She just moved schools in September (both state schools) and her new school at her last parents evening asked whether we'd been thinking about grammar school applications for her. We hadn't really thought about it and now I've read that most parents are getting their children to prepare from year 4... We wouldn't be taking a high pressure approach to it; just some practice papers, lots of reading and maybe an app subscription so is it far too late?
I know it's tricky to answer as a lot comes down to aptitude and how well a child can perform under exam conditions, but does it sound unreasonable to try?
