I can't seem to find the past papers and mark scheme for Unit 1 and 2, all the ones on Edexcell's site are on "secure download", you need some sort of login to download it. Where can I get the past papers and mark schemes from? Thanks in advance.
You can't get them unless someone has downloaded them and uploaded them to a different site.
If you ask your teacher they'll be able to print them off if they have a secure login.
There are specimen papers for all units under the 'Specimen papers and mark schemes' bit, but there's only 1 higher & foundation for each unit - and there are no UMS boundaries so you can't tell what grade you actually got.
