How long is the registration period for the orientation meeting?

M: Do you have a minute?
F: Sure. What’ s up?
M: I just want to go over the schedule for Wednesday’ s orientation meeting to make sure everything is ready.
F: Ok. Here is a copy of the tentative schedule. Now, the registration starts at eight thirty and goes until nine fifteen. Then, the orientation meeting will commence at nine thirty.
M: Ok. Now, we had planned originally for the meeting to go until ten thirty, but now we have someone from the international center coming to speak to the students on extracurricular activities, so how about ending the meeting around eleven?
F: Fine. And, then students will take the placement tests from eleven fifteen until noon, followed by twenty minutes break before lunch. And, immediately after lunch, we have reserved a campus shuttle to give students a 45mintutes tour starting at one thirty. We want to show students around the university, including the union building, the library, and the student services building.
