No, I don’t think so. More of university level. Some introductory, some advanced. What exactly are you looking for? Subject, topic, level? You would be surprised at what google might throw up if you play around with different keywords and operators. I was initially looking at maths basics, refreshers and advanced resources on the net, as well as open courseware and ended up bookmarking lots of stuff I liked. I have loads of maths links on precalc, trig., calculus and university level courses. I think I have some GCSE, A level, high school revision sites in my bookmarks as well, but I didn’t conduct a comprehensive search for these qualifications. Just came across some topics that interested me and I bookmarked them temporarily till I get the chance to sift through the material (about 100 math links). So, if you are looking at specific syllabi etc., try a google search. If you can’t find what you are looking for, then drop a post about specifically what subject and what topics are covered as well as what you want from the search and maybe, ppl on the forum might be able to find the material.
Edit: Apropos previous photoshop query, came across a digg article

I don’t know much about O’Level syllabus and testing. Try Google search. Playing around with operators and keywords can yield some very useful materials.
Anyways, here are some sites that although they may not be specifically geared to O’levels, they may still have some similar/same topics.
Some math vids
Math review site
Click on a course, then on-line lectures, some useful realplayer vids
Some O level resources, Various O level subject, some past papers
Elementary high school math
Nice topics. Useful
BBC GCSE BiteSize
Some GCSE, A level and SAT
mathtutor.biz youtube channel (vids searched for gcse)
“Mathematics tutorials are suitable for anyone in secondary mathematics education, particularly those in the age range 11 - 16+.”
