being a pledge

As long as you're not skipping chapter, new member meetings or any other mandatory events you will not be restricted about going home at any point :)

Also, sororities don't use the term pledge. You'll be a new member when during your first semester and a full initiate after you complete the new membership period.

You won't be kept from going home during your new member period, unless there is an event or meeting that you need to attend. However, as tempting as it is to go home on the weekends, especially since a lot of people at Mizzou live so close by, try to avoid it. Your best memories with your new sisters will be made on the weekends, not in class. I don't even mean solely partying.. Going shopping, hiking, just hanging out at your new house is so much fun and will show that you are open to making new friends and getting involved in your chapter.

If you have to go home for a personal reason and you talk to who ever takes attendance in your sorority, you can still go even if there is an event that weekend! You probably won't want to miss out on any events though unless you absolutely have to!
