In which section should the students write their UK address? What is the school’s postcode?

Jeff (male): Hi Aref! Hi Marta!
Matra (female): Hi Jeff2.
Aref (male): Hi Jeff! Thanks for agreeing to help us with this university application form.
Jeff: No problem. It’s the UCAS form, is it? Well, I brought mine along as well as an example. Let’s have a look at the first page. ... Ah, here, you need to write in your addresses in your home countries.
Marta: Here? Where it says "home address"?
Jeff: That’s right.
Marta: But we don’t want them to send things to that address.
Jeff: They won’t. See. It says they will send things to your residential                  Q21
    address, which is in the UK.
Marta: Oh, I see!
Aref: And here we need to write the name of our school, don’t we?
Jeff: Yes, and any other secondary schools you’ve attended. Don’t forget to write "FT" in the box there on the right.
Aref: "FT" means "full-time", I suppose?                                   Q22
Jeff: Yes, it does. Put the most recent school you’ve attended at the top.
Malta: Here it says we should enter our ethnic origin, but only if we are UK applicants.
Jeff: Well, you are living in the UK. Put it in anyway. It won’t matter.
    They only use it for statistical purposes.                             Q23
Aref: Should we put the subjects we’ve taken for A-level in this area—7A?
Jeff: No. That’s for exams you’ve already taken and got the results
    for. Here, underneath, in part 7B, you can see the space for                      Q24
    exams that you’ve taken but don’t have the results for, or are
    going to take.
Malta: And do we need to write the name of our school there too?
    That’s where we will take the exams.
Jeff: That’s right. Don’t forget to put the address too.
Aref: Do you know the postcode for our school, Jeff?.
Jeff: Yes, it’s PL3 6LY. Now, how about page 3?                             Q25
Marta: I did some part-time work. Should I put that in the employment section?
Jeff: Yes. I did some part-time work too. Write "PT" in the final box—for "part-time".
Marta: OK. And for "nature of work" I’ll put "shop assistant".                   Q26
Jeff:  OK. Now we’ve come to part 10—Personal Statement. Did
     you write out a rough draft for me to look at, as I suggested?             Q27
Marta: Yes, here’s mine.
Aref: And here’s mine.
Jeff: OK. Let me just have a quick look  ....  I’ll just correct the
    grammatical mistakes. There aren’t many  ....  Be careful with
    your spelling, Marta  ....  Aref, I wouldn’t include this sentence
    about wanting your parents to be proud of you. A personal
    statement should be more practical, rather than an emotional              Q28
    appeal.
Aref: I see. It’s a bit different in my culture. OK, I’ll take your advice.
Jeff: I think that you both need to say why you’re interested in those particular courses at those particular universities.
Marta: Well, I like some of the elective courses on offer in years two             Q29
     and three. That’s how I chose those particular universities.
     How about you, Aref?
Aref: Well, I considered that, but many of the law courses at university  are very similar, so I also considered the geographical location of the universities.
Jeff: OK. Add those reasons. Have you both signed at the bottom of page 3? ... Yes, oh, Marta, you forgot to add the date. Now, on page four, you need to have a teacher write a reference for you.
Aref: I’m going to ask Mr Martin, since he’s my form teacher.
Marta: I’m going to ask Mrs Robinson, because she’s my art teacher.
Jeff: Good. It’s best to have your form teacher to do it or ask the
    teacher who teaches the subject you want to study. They are
    most likely to have an idea of your abilities.                           Q30
Aref: Should I leave it to the teacher to fill in the details about the school at the top of the reference page?
Jeff: Yes. Some of that information isn’t known to us students anyway.
Marta: Well, thanks for your help, Jeff. Are you going to ...
