I know I have mentioned this before, but the All About History Magazine which is now into its fourth issue goes from strength to strength. It is perfect for revision, very readable and full of useful facts. there is usually a 15-20 page themed section every week (Explorers being the most recent) which I am finding very useful indeed!
I was a bit sceptical but its been well worth spending time with. I would be very interested to know other peoples opinions on this title?
