OCR A level biology new syllabus

Who is doing the new biology OCR syllabus on here? What do you think of the specimen papers that OCR gave? Is it me or are they really difficult?? I got an A* in GCSE and i can get a good A in the past papers upto 2014 on OCR's website.... But on these new spec papers i get like 59% and i have no idea where i am at with that sort of grade...... Is anyone experiencing the same problems?
