I've been studying (albeit very slowly) for Network+ for the past six months. I've finally decided I want to get this out the way now so that I can get my MCSA certification (I already have A+, M$ exams 70-210, 70-215, and 70-21

.
I've just completed the practice test and scored 76.7%. I know I need to brush up on OSI, Network Segments, Port Numbers and AppleTalk. Is this score good enough for a pass???
Of all the exams I've taken this one I seem to be most nervous about and need to be confident I'll pass before I take it. Any tips appreciated.
TIA
