Do you mean "will June 2014's A2 exams be harder than A2 exams from previous years?". If so, I think it's possible. I know from experience that the exam board CCEA has really made their maths and physics exams a lot harder this year and friends have told me that CCEA have asked morre bizarre or difficult questions in Economics, Moving Image Arts and English.
Both my C3 maths and Physics Unit 2 exams were far harder than any past paper (C4 turned out to be all right though, thankfully and I haven't yet done Physics Unit 2)
However, I haven't sat any A2 exams from any other exam boards yet so I don't really know if their difficulty will also be stepped up. My advice would be to prepare for the worst and expect and exam far harder than any past paper. If the paper turns out to be fine, then you'll still feel good so it won't matter.
