Hi! I found a firm which says that has course for people who want the Cambridge A/AS level in computing professional diploma! As I am not a UK nor USA resident I like to find more from you about this diploma… Maybe some of you even has it… It is worth something?? I found on a site that is designated for 16-19 years teenagers 
Can be this diploma a good start for getting a job in the IT domain? Are employers seeking this kind of qualifications??
A level and AS levels are UK qualifications taken by 16/17 year olds (year 12) and 17/18 olds (year 13). If I remember correctly the AS level is worth half an A level. I have no idea as to if they are worth anything outside of the UK
