I’m currently doing gcse photography (aqa), and my sixth form is also offering it for A-level (also aqa). From what I’ve heard from my teachers and a level students, in AS you do two main projects - portrait and landscape. In A2, you’re completely independent and throughout the year come up with one big project - all of the ideas I’ve seen and heard about were amazing!
From open days in colleges, people told me that you’re more independent, since the start of a levels. You’re not told by a teacher what exactly to do, what type of photography/what theme you’re required to do.
Personally, I’m considering doing it for a level, however it’s only offered by the sixth form, and the college Id rather go to doesn’t offer it, unfortunately.
On the other hand, photography is a VERY heavy when considering the amount of time you need to put in. I’m planning to do maths, further maths and physics for a levels, and I’m worried that it’d just be too much - as I can already tell you that gcse photography was very very heavy in work, and I spent an enormous amount of time (at the end of the day, it paid of!).
To conclude (btw sorry, this is longer than I expected), it depends whether you’ll be in college or sixth form, and how advanced you are - I’m a pretty advanced now (considering my digital skills as that’s my hobby), therefore my teacher told me I’d not learn many new things in a levels. But if you’re an amateur and would like a helpful hand to lead you through AS, then a sixth form is a great place to take photography - but keep in mind the amount of time you’d need to put in...
