The SQA web team has been working hard over the last few months to improve the SQA website. Each subject now has its own home page and the (vocational) Computing one is full of useful information.
I checked the Computing home page this morning and found arrangements documents, FAQs, update letters and the whole host of other helpful documents there. We recently uploaded a report on Next Generation User Skills [PDF], which describes the IT skills that will be needed in 2013.
There are also dedicated pages on specific Computing qualifications, such as PC Passport and Internet Safety.
So, it's a page worth bookmarking.
