I think most of his mid-year ones were out of books, which he's now undoubtedly scribbled answers all over now.
He'll be in the same boat as me, plenty of resources to share for end of year exam but almost nothing for mid-years.
Erm... for anyone that doesn't use the cambridge textbook, these may come in handy as additional references:
http://rapidshare.com/files/121321006/cambridge_units_3_4_textbook.pdf.htmlhttp://rapidshare.com/files/121320341/Templates.zip.htmlThe first link is the textbook, and the second is a zipped folder containing the templates for the chapter reviews for chapters 3, 4, 6, 7, 8 and 9.
I think the chapter reviews for this textbook emulate exam-style questions quite well (which may help to explain why I did so few practice exams).
While I don't have the answer pdfs any more, there are answers to a lot of the numerical questions on the last page of the textbook (and you can always ask ppl on this forum).
Unfortunately I've lost the templates for 1, 2, 5, and 10 - 12, so please don't ask me for them. I've hunted through all my back-up discs and everything to try to find them for you guys, but they've remained ever-elusive.
I'll post this in that other thread as well...
