I’m a HS/AA, so I know I won’t have a regular preview date with other freshman. I went to register for freshman preview, and saw that the only session they have available is on August 18, which is pretty late in my opinion
The only preview for us was June 22
HS/AA
I remember when I first got admitted, they sent an email with the preview brochure that stated that HS/AA preview date was Junee 22-23. But when I went to register the only session that was an option was April 18. I guess its because I registered so late. I just hope that I am able to get good class times and even get into the classes that I need for my major 
They save spaces in all the common freshman classes for the later Preview dates.
I wouldn’t worry too much. When I was a freshman, my date was after that, and I got everything that I needed for classes, etc.
Don’t worry! They save classes for each section of Preview to ensure that each student have an equal chance at choosing their classes!
