Easiest a levelsWatch
It also depends on the person. I personally don't find physics particularly challenging for the most part, but sociology and english would eat me alive. I can also confidently say that the sheer amount of time and consideration needed for a subject like Art (including photography and textiles, which all follow the same course outline) vastly beats out the time most people would need to spend studying a science A-Level.
Which a levels are easy to study? I think these a levels are easy to study: a level media studies, a level film studies, a level photography, a level art, a level sociology, a level politics, a level law, a level english language, a level business studies and a level textiles. Please correct if I'm wrong.
I would say an 'easier' A-level is health and social. A lot of people (tbh girls) who failed A level's and didn't go to uni ended up doing that the year after and most went onto nursing degrees with a double award in it. I can't exactly remember the content of the subject (two of my friends did it for sixth form), but compared to my work it seemed a lot easier. Also, a girl who was studying A-level Law, English and History dropped all three so she could do double award health and social and become a nurse.
Also, A-level English is in no way easy! And this is coming from someone who is currently doing a Masters in English Literature! Personally, A-level English was way harder than both my degree and masters! You couldn't pay me to re-do it!
