The above files are ZIP files. You will require 7-Zip to open them. Within these ZIP files, there are PDF files. You can use Adobe Reader to open these files. Both these above programs are free.
If you're looking for the Heinemann Text Books for Edexcel Maths, try here.
The only one that are legal are the ones given on the edexcel website. I'm gonna have to edit the posts to get rid of the elmwood/solomon (Sorry, looks like you went to some effort making the post!) and the links that aren't on the edexcel website.
Are you sure it's even legal to publicise these papers ? Copyright and all that and all that.
As I told the Mods, I'm not actually hosting these papers myself.
They are simply links to places I found these papers. Well ok maybe the Solutionbanks I have put up but look, they are Passworded!!
Now as I recall, nowehere on TSR does it say it is illegal to place links to Papers. Actually I've been told it's allowed several times.
I thought long and hard about this, and avoided all possible problems yet there seems to be unclear rules still. I will try to get the content replaced, once things clear up, if I can.
Theres another good one, KHAN Academy. Lots of maths videos ranging from fairly easy algebra/arithmetic to some pretty interesting calculus/ differential equations.
