M: Rachel, did you find it hard, studying with the Open University?
W: You mean, because you’re studying on your own, most of the time?
M: Mmm.
W: Well, it took me a while to get used to it. I found I needed to maintain a high level of motivation, because it’s so different from high school. There’s no one saying, "Why haven’t you written your assignment yet?" and that sort of thing.
M: Oh dear.
W: You’ll learn it, Paul. Another thing was that I got very good at time-management because I had to fit time for studying round a full-time job.
M: Well, I’m hoping to change to working part-time, so that’ll help.
W: What makes it easier is that the degree is made up of selective courses, so you can take time off between them if you need to. It isn’t like a traditional three-or-four-year course.
M: That’s good, because I’d like to spend six months travelling next year.
W: Huh, it’s all right for some. Then even though you’re mostly studying at home, remember you’ve got tutors to help you, and from time to time there are summer schools. They usually last a week. They’re great, because you meet all the other people struggling with the same things as you. I’ve made some really good friends that way.
M: Sounds good.
