I took (and failed) JMB A-level Physics back in the 1980s and am interested to take A or AS level Physics again as an external candidate. As things have changed over the years I'd be grateful if you could answer some questions about the course. 1) What are the basic differences between A and AS level? 2) I presume A-level still has compulsary practical work but does AS-level? 3) Is there compulsary coursework? Can this be done as an external candidate? 3) Is it possible to take A or AS-level in one year? 4) What's the format of the exam? Is it still 3 papers in June? Thanks.
