For my reference
Past papers for Edexcel
HERE (Plus other subjects)
Explainingmaths.com I realy like this as it caters for IGCSE Maths, and if The Boy is stuck I can send him here as it is all set out nicely. Lots of youtube videos that you can access throught the website or directly from youtube
Maths Takeaway Great little quick revsion site.. great to test knowledge or to have a break from past papers
Mathasaurus Links take you to video’s which exlpain the diffrent topic areas easily understandable. Does say GCSE but also link to IGCSE – past papers included here.
This looks good and may be useful to sign up to nearer the exam for help with revision etc.. We haven’t tried it yet but worth a look Absolute Maths
Map of Mathmatics – rally cool explains how all Maths is linked.
Save My Exams Great for Maths but also has resources for all the science. At IGCSE, GCSE, A Level etc.. some free, but to get the most out of the site it is best to subscribe to full membership – not too expensive.
