Application Question!

Hi! I am filling out the UGA application and on there is says I have to list my school and community activities. There is a 300 character limit on each activity I enter and I am having a real tough time entering in all of my involvement since freshman year into the word limit. So I was wondering, when entering in the information for each activity, should the descriptions be sentences or can they be bullet list style? And not just for UGA but for other colleges as well since they all have a word limit.
Thank You!
