Check if the form code and UF ID number you bubbled-in are correctnow
. Also check tobe sure your name is correctdo it now. I investigated the rumor that the ability to
correctly record these had been mastered by a few students at FSU. This rumor turned
out to be false. But, the rumor that an accounting major and a journalism major did
successfully record these on a test is true. These students have since been bronzed and
are on display outside their respective colleges to serve as an inspiration for all other
accounting and journalism students.
CHECK YOUR FORM CODE AND UF ID NUMBER. IF YOU GET
EITHER OF THESE WRONG, YOUR TEST MIGHT NOT BE
GRADED AND IF IT IS GRADED, YOU WILL LOSE 3 POINTS!
