I also fine it really helpful to have a list of things to do. I'm not as organized as some others, and I do sometimes forget about classes (I did all of HOL 101 in the last 4 hours before it was due). I have a calendar with all of the important things that I need to remember to do, which I check every day.
I'm so excited for summer. I was away and unable to check HOL at all for the first part of last summer, so I missed a bunch of fun activities, which I was sad about. I'll be staying home this summer, so I'm excited for those! I love seeing what classes there are at the start of each term, so I'm super excited for that in September.
