if your doing your IGCSE/GCSE i dont recommend save my exams because i found those questions really easy, even the gold level... why dont you try actual pastpapers from DynamicPapers.com, its much better.

good luck
The gold questions were sort of hard for me do u know any way i can get the mark schemes
if you mean in DynamicPapers, they have full papers not titbits like in Savemyexams. doing full pastpapers are useful so you revise both the easy at the beginning and the hard at the end, so you dont enter the exam forgetting how to do the easy ones.
