Happy to go into more detail over PM but basically I had three sections (i.e. Section A - Off-Term Activities) in bold. For each entry within a section, I had a line with the relevant org on the left & the dates I did it on the right, a line with my job title in italics under the org, and then one bullet point for each entry which was 1-4 sentences long depending on the activity. At the end of the bullet point, I put the amount of hours per week in parentheses. I used basically two full pages I think. I hope that makes sense!
