I find all my subjects easy, since I took quite easy-to-understand subjects - no sciences (since Psychology isn't generally considered a 'real' science subject at AS/A2!) and I dropped History because I didn't have the motivation to put in the volume of work. In order of how enjoyable they are, though: English Lit., Religious Studies, Psychology and History.
Maths - because I'm not great at Maths English Lit - Easy for me, but there's coursework and my teacher set homework every lesson which was very time consuming. Politics - Lower level of homework than English
Chemistry - Loads of stuff to remember Further maths - I found some concepts fairly hard Physics - Generally ok but would often loose marks on explanation-type questions Maths - Really easy
For year 12 in terms of effort required rather than difficulty, hardest to easiest: Computing (epic coursework required and really really picky examiners) Physics Maths A2 Maths AS
Year 13: Physics Further Maths A2 Further maths AS
Physics/chemistry/maths were very very easy. Biology was harder because I don't like essays. Further maths was the only really hard one (FP2/FP3 were not fun)
