Wanted to upgrade Mbp 13" ram to 8gb.
Not so easy to get the screws out with a tiny flathead screwdriver I had. One screw started flaking off a little so I stopped and ordered the basic 00 philips from ifixit. EZ with the hq screwdriver.
Be sure and get the spudger and go ahead and disconnect the battery, it's not worth the risk of leaving it attached. Spudger will come in handy on other tasks and is cheap.
