Hi, not seen your other thread, but this was the sort of thing (amongst all the others) that worried me too, but here we are doing them. :)
The answer is some do and some don?t and some do a lot, and some a few, and some talk about them a lot, and others don?t, and some prepare for them from the begining and others don't. :)
We?re structured H/e taking Igcse,s and A/S levels, who to paraphrase Mum in Scotland, like to ?build ideas in a subject, up over time?, but have friends who?ve always been autonomous who?ve suddenly gone after the same exams.
I wouldn?t have dared take that road, but they don?t seem to be having any difficulty filling in any parts of the syllabus that are new to them. :) (Exam technique?s something you have to understand when you get to that point, but there?s plenty out there to learn from.)
For us we simply study the same exam syllabus?s as schools do, ie Exdecel, AQA etc, and use their textbooks as a syllabus framework, but do it our own way (ie physics; understanding forces and motion on a surfboard rather than a blackboard, and our geography river coursework was done in the river) and tend to read around it more as there tends to be more interest in the wider subject as a whole, (ie studying Rosetti for English, threw up fascination in where the reform house she?d worked in had been exactly which isn't part of exam syllabus) rather than just the bits that get examined.
But just to reassure you whilst there?s many different h/e paths, for those wanting standard exams later, college and uni, it?s all perfectly do-able, and you don?t need to have always done a curriculum, or done exactly x,y, or z by x age or be doomed. :)
