Freshmen orientation and class registration

<p>Hi all,
My D is going to have a summer trip that blocks out most of the Summer Orientation schedules. She is thinking of registering for the first session in early June before her HS graduation ceremony and the trip. However, the AP scores from this year will not be out until July. How would that affect the class placement and registration? Does it mean she may need to change her class registration after the AP scores are out if that may affect her placement?
There are a couple orientation sessions available after the trip, but I am not sure if she will be recovered from jet-lag before that. Also, she is trying to avoid the final Fall Orientation.
Thank you in advance for any advise.</p>
