It's widely accepted that A levels were at their easiest during the noughties (2000's), and it got so ridiculous that they made it harder in the 2008 change of specification, with it getting increasingly (but only slightly) year on year.
If you compare a 2016 maths or chemistry A level paper with a 2005 paper, you would clearly see that it is currently much harder than back then, when it was just stupidly easy.
Still doesn't compare to the 70s and 80s though, those were really hard.
