giving schools a resume seems rather redundant. the OLSAS sketch has 96 entries so you can link, say, 5 of them to write a detailed description of an activity you have done. i'm having trouble filling in even half of those.
you can use as many possible consecutive entries on the sketch to elaborate on an activity. you just put the same date/location and then use the activity field for continuing your description. a resume would be a hell of a lot easier, though.
