Narrator Listen to a part of a conversation in an office. How long has Andrew worked at the hospital?

[Visitor] Hello, May I come in?
[Teacher] Yes, please. Can I help you?
[Visitor] Yes, I was told to come here for advice about, erm, Management Diploma courses?
[Teacher] You’ve certainly come to the right place. Hi, my name is Monica.
[Visitor] Nice to meet you. My name is Andrew, Andrew Harris.
[Teacher] So, Andrew, are you completely new here?
[Visitor] What do you mean by "completely new"?
[Teacher] I wonder whether you have seen our diploma course prospectus yet?
[Visitor] Yes, I’ve already looked at it. In fact, I thought the information on course content was really useful, but I’m afraid I’m a bit confused by all the different ways you can do the course: full-time intensive, part-time and so on.
[Teacher] Well, let’s see if I can help. I think each course type has its advantages and disadvantages, so it really depends on you--your own study habits, and your financial circumstances, of course. Are you working at the moment?
[Visitor] Yes. I’ve been working in the administration section of the local hospital for the last three years. And before that I worked in the office of a computer engineering company for two years. So, I’ve got about five years of relevant work experience. And what I’m hoping to focus on is Personnel Management.
[Teacher] I see. And are you planning to leave your current job to study, or are you thinking about just taking a year off?
[Visitor] I want to know what my options are, really. I don’t want to quit my job or anything and my employers are keen for me to get some more qualifications but obviously, it would be better if I could do a course without taking too much time away from work.
[Teacher] Right, so you don’t really want to do the full-time course, then?
[Visitor] No, not really. It’s also a question of finances. You see, my office has agreed to pay the cost of the course itself, but I would have to take unpaid leave if I want to study full-time and, well, I don’t think I could afford to support myself with no salary for a whole year.
[Teacher] OK. Well; you have two other possibilities: you could either do the part-time course--that would be over two years and you wouldn’t have to take any time off work---or you could do what we call a "modular" course. You could do that in eighteen months if you wanted, or longer, it’s quite flexible and it would be up to you.
[Visitor] Mmm. So what does the part-time course involve?
[Teacher] For that you would join an evening class and have a lecture twice a week. Then, you’d have to attend a seminar or discussion workshop one weekend a month.
[Visitor] What kind of course work would I have to do?
[Teacher] Well, it’s a mixture. You’d be expected to write an essay each month, which counts towards your final assessment. You have a case study to do by the end of the course, which might involve doing a survey or something like that, and also you need to hand in a short report every four weeks.
[Visitor] So, that’s quite a lot of work, then, on top of working every day. It sounds like a lot of studying-- and really tiring.
[Teacher] Yes. You certainly wouldn’t have much free time!
[Visitor] Then, what about...
