Schools are all so different! DS3 has his 'official' exam timetable printed on yellow paper, but it was just given to him, not me. I only knew to look out for it because DS1 and 2 had the same (and DS1 was more forthcoming!)
We haven't had an email from the school about exams since Feb. We did have a parents' meeting in Feb as well but it was more about revision guides, eating well, sleeping well etc.
Each exam is probably on the school website calendar. Will go and check. If your DD has it all under control, lljkk, I'm sure that's fine. You are in the minority on this thread, though!
