If I remember correctly. Mon-fri 1 once a week you drive. Saturday only once. You Swap alternate weeks. The month was 31 days long. Therfore 4 weeks atleast. So 6x4 = 24, 24/2 = 12. Now the 3 days left could be Mon-wed. Therefore 3 more days for someone. Since maximum number of days I then said 12+3=15.

Oh, I remember it as driving alternate days (and Saturdays happening every other week). Dang it, might have misread it then.

Is this right?
I calculated it as

5x4 (mon-fri)+ 2 (saturdays) + 3 (mon-wed) = 25

25/2 -> 13 and 12

Think I got CBBC for the first four?

I also know I got a triple CCC and a triple BBB at some point haha
Me too! I found myself putting lots of Cs at the start and then lots of Bs midway through :/

Nah dude it's 13. The most possible for them to work is 25: 5 Thursdays, 5 Fridays, 3 Saturdays (every other but assume that they come into the month having just skipped a saturday), 4 Mondays, 4 Tuesdays, 4 Wednesdays.

(5x2)+3+(4x3)=25.

If they swap strictly every other day then the maximum would be 13.

Um, the clock was 30 min slower than HER WATCH, no? Maybe I read it wrong. I got E, on time.
Thank f**k, some one agrees with me!

9. this is what it would look like on a calendar with the days they don't drive crossed out, 25 days of driving, whoever drives first drives for 13 days

I didn't get an A till around 11 or 12 I think haha.

In other news, does anyone know how Oxford apply the Rasch model to the TSA. Is it that certain questions give different point scores on the TSA model or what?

Fail to see, otherwise, how I managed to get above the cutoff last year when I did the same as this year (didn't finish the paper lolz).

What tsa score did you get ? so I suppose you got an interview for ppe (?) at which college ?

I feel the same about having too many c's and almost no a's till the end to the point where I considered guessing a's for the last two questions because of the stats haha
12. Did people finish all the Questions? I had to guess without looking at the question, for 5-6...

Haha! I'm not too sure it was in the 60s and must of been above 61 (the cutoff last year) can't remember the exact score though. Yeah it was for PPE at Catz.

hahaha I guessed BBBB for the last four and apparently 50 was B which is a win considering there was a 4/5 probability of getting only one of them right hahaha.

I did practically the same, and looks like a lot of other people did as well!

With the Rasch Scale people who actually took their time for the last questions and got them right will probably be able to boast their score quite a bit haha. I put b for 50 I think... What did people put for the arnorld and traffic light question ? Had 13 for the working days question I think

Fairly sure the answer was a, 5 minutes, I don't think it i necessary or the car to stop at either traffic light

I think mine was that it had to wait a the first one but could go through the second one...
18. it wanted the LONGEST TIME it could take for him to get to work so it was D, 9 minutes. It took him 100+80+180=360s to do the bits inbetween = 6 mins plus 3 mins at traffic lights.
19. F*ck I thought that calendar month means 30 days. In that case 13 is correct. Not 12
20. Every question scores one point on the TSA. Anyone who says that questions towards the end count more has no clue what he is talking about.
However, a Rasch curve for TSA usually transforms low raw scores (e.g. 1/50) to high Rasch Scores (e. g. 14). Very high scores earn their high Rasch Scores. However the medium scores are pretty much leveled out so that each additional point in the midfield only adds relatively little to the Rasch Score. The curve would start high, rapidly rise, slowly rise (middle scores) and then rapidly rise again (high scores).
