The 8th grade EOG has 60 questions to be
done in an estimated 180 minutes. More
time is allowed to those who have not
finished, up to a maximum of 240 minutes.
The EOG consists of 4-choice multiple
choice questions and gridded response
questions.
The multiple choice part of the EOG will comprise
approximately 80% of the test while the gridded
response part will be the other 20%.
Gridded response questions require not only a
correct answer but a proper gridding in the grids
provided by the State of North Carolina.
Correct answers must be carefully
gridded for the students to receive
credit.
The 8th grade EOG
contains questions that
are both calculator
active and calculator
inactive.
Approximately one third
to one half of the EOG
will be calculator
inactive, the rest
calculator active.
