Thank you for contacting us regarding your exam day related question. We prefer that you write your answers to the constructed response questions in ink; however, the graders will certainly grade any answers you write in pencil.  Writing in pencil will not affect your exam grade.


Feel free to contact me again if you have any other questions.

Warm Regards,
