Change of Final Exam Schedule

The second year students of the Biomedical Laboratory Technology program at Dawson College are concerned about the Winter 2019 final exam schedule. The original schedule was:
Clinical Chemistry 3: Friday May 24th from 14:00 to 17:00.
Clinical Hematology: Tuesday May 21st from 14:00 to 17:00

The preferred schedule would be:
Clinical Chemistry 3: Tuesday May 21st from 14:00 to 17:00
Clinical Hematology: Friday May 24th from 14:00 to 17:00

The dates and the times do not change, only which exam is taken.
