but I had a 27 average going into the final which I made a B on (which would have been a B+ with the addition of +/- grades the following year). Thank god the prof's policy was that final grades would not be lower than one letter less than the final exam. I opened that book those last three days of the Quarter and got it down enough to pass (none of which I recall 40+ years on). Books, they'll get after ya!
