I have developed a database driven website which shares past papers, markschemes and my own ‘write outs’ for most Edexcel modules in mathematics and further mathematics:
I use this mostly as a resource for my own teaching; using it I can lay my hands of exam questions and solutions of different types very quickly. My students and pupils find it useful too because it shows how to do exam questions using the techniques taught in class; there is an important difference with mark schemes here.
The UK mathematics exam system is in a state of flux at the moment. I see this is as a great opportunity to review and refresh all my teaching material. I look forward to generating new material to support a revised school exam system.
