The answer sheets and request form are left at the Computer Centre for scanning and processing. The Computer Centre scans and processes the answer sheets. If the scanner records that a student has two marks for a question, the student's answer sheet is checked by the operator. A printout is produced with the requested reports. When the printout is ready, the professor is called to pick up the answer sheets and the printout.
Results are usually ready within two working days.
If examination of the marks and question analysis identifies questions that should be omitted or answers changed these corrections may be requested and the exam analysis rerun. For example, an exam might have a true and false section with each question worth 1 point and a multiple choice section with each question worth 2 points. Questions may be omitted or have more than one correct answer. Wrong answers may be given negative points, but this is not recommended as the scanner may read erasure marks as valid answers. A biserial correlation coefficient of less than 0.15 indicates that the question did not discriminate between students of varying ability.
