I've been working at learning programming for a while now and I feel that I could benefit from becoming a paid member, and be able to test on device, however £59 for a year is little steep just to test on device, before I even think of going to the app store. Is it possible for a student in high school to get any discount (even £3) (I know that some companies offer software to students for free, so I thought this may apply to Apple and the iOS developer program)
Apple has a University developer program. It's explicitly for higher education institutions, but a representative of your school district might be able to convince Apple to let them join. For everyone else, the price I've seen is $99/year.
