DS is about to start boarding school in September as a 3rd former. He's just finishing off year 8 at an international school. I'm aware that its a very long holiday this year and that the majority of new entrants at his new school have been to prep schools where the standards are much higher. Also he's missing the last two weeks of school abroad.
I'd like to do some science with him over the summer holiday, to prepare him for his next school. It would have to be online. I've seen a few names of apps/online courses in previous conversations; Tessomai, Seneca, Mygcsepod etc but don't know a lot around them. Do any of them introduce GSCEs in a fun way eg through videos and quizzes? Or do they just test? Just testing is not useful to me as he won't know the material. His next school starts the gcse course in September so that would be more relevant than recapping key stage 3.
