G-325A Question

[An-chan 1]

So, I'm filling out my G-325A to get it sent to my fiancé so he can eventually send the petition, but I'm a little confused over the employment field in the form. Namely,

1. If I've worked odd weekends and sales at one store for several years, but never more than about three weeks at a time, how do I go about entering that information into the form? Do I enter it at all, since none of the periods of employment lasted even a month? Has anyone had any experience of this?

2. Since it tells you to put in your employment for five years, I should include my high school, right? (I was in high school 2007-2010)

3. I was unemployed for several months after high school. Can I lump this in with the "unemployed because I was a high school student", or are they different entries?

Also, how do you make an extra sheet with this information? Do you just follow the same format (company name + address, occupation, starting time, ending time) or should you add in extra explanation or what? I feel silly filling this out when all of my employment has been seasonal jobs, and the rest of the time I've been unemployed either because I was a student or because I was applying into a school. That's not going to affect the petition, though, right?

Sorry if I'm a bit neurotic, but it's all new to me and the amount of paperwork is pretty astonishing... Any help is appreciated! I'm so glad a forum like this exists!
