From April 28th to May 21st, International Baccalaureate(IB) seniors around the world take IB Exams.

Different tests vary depending on time zones, but all the school within the same time zone receives the same test. The length of the exams varies from test to test; the shortest test lasts 45 minutes, and the longest test lasts as long as 2 hours and 15 minutes. Each subject is divided into different sections, some being multiple choice and some being subjective. Seniors should arrive at least 45 minutes to be mentally prepared before the exam starts.
On the exam date, students are only allowed to bring writing materials, calculators, and a bottle of water. Students will be under supervision, and any actions, even going to the bathroom, will be monitored. Before the exam starts, teachers strongly recommend going over past exams and planning how they are going to attack their exams and time management strategies. When a student is sick on the day of an exam, they need a note from a doctor for being unavailable to take the exam. Depending on circumstances, some students may or may not have to take a different test.
As the test ends, the exam papers are sent to IB scanning centers and distributed to IB examiners all around the world. Examiners do not know the names of students who took the test for fairness. Seniors will receive their grades on July 5th or 6th. The tests are released to the school for 12 hours.
