Hi.... Same two screws on a mid-2013 model Mac Book Pro. Apple changed their automation process so that these screws are put in by machines (they started this at some point in 2012 it seems). So it's next to impossible. Apple stores have special power tools to get them out, it's almost impossible with hand tools without stripping them... The answer is to invest in a costly power tool for this one time job or simply pay Apple.
All the positive press you see about the Mac Book Pro's being easy to matinee is false. It applies at best to some models that didn't get super tension screwer (maybe the robot that built ours was just having a bad day... I don't know, don't care hope Apple's entire QA team burns in !@#$ over this... That's harsh but when you pay top dollar for what's advertised as the Lexus of computer you expect more than just some Chinese built POS that can't even be opened). Sorry there is the hard truth.
