Post-UCAT Discussion 2020

[dande]

It does get hazier the higher you go, but when I used last year's mean + s.d. to extrapolate percentiles above 95, after comparing it with the official calculator, I was off by 10 at the most.

whats SD this year?

 

[dotwingz]

whats SD this year?

mean 2512.02, sd 318.327

Ill post my full working up some time.

Damn, a 900 in SJT? If that’s even remotely possible then your friend is on his/her way to Monash

Or not, depending on which Monash admissions officer replies to your email

Whaaaaaaaaaaaaaaaa... maybe this might be an error. (content removed: seriously dotwingz i absolutely know you know better re. this rule, from LMG).



UCAT is not perfectly normally distributed. IIRC last year some scores went up +- 1% from my old calculator, but its generally not to bad of an estimation

I'll ask my friend for a screenshot of his results, and hopefully by September we'll see if he's true or not

 

[dande]

does anyone know SD for SJT?

SJT isn't normally distributed, so a S.D. figure is essentially meaningless. The SJT deciles should give you a good guide as to where you fall, that wasn't available last year.

It’s not normally distributed, so SD for SJT isn’t worth calculating.
EDIT: ucatboy is too fast

 

[dotwingz]

does anyone know SD for SJT?

mean = 612.96
sd = 49.954

Although this figure is essentially useless because SJT is not normally dist, just check how broken my calc is with SJT and you'll see

Also real quick, is that calculator based on the percentiles of each section sort of and then averaging it out or is it from the total cognitive score?

Total cognitive score

 

[ucatboy]

mean 2512.02, sd 318.327

Yo I think the summary statistics report specifically states that the mean score is 2527.



Is 2512.02 and 318.327 the inputs you used for your calculator?

 

[soulja]

Asking for a friend: he got atar 97.2 and an UCAT score of 3050 and he's wondering if it's competitive enough? Thanks

wait for percentile calculator

Yup, will fix it. mb

Does anyone know how important Situational Judgement is as a consideration for Monash? Because I know Monash the only university that considers it and I wasn't sure if a score of 619 would significantly affect my changes. My score for the cognitive subsections was 3120 and I hope that my Situational Judgement score doesn't affect it too severely. I couldn't find any information on the Monash website on how they use the Situational Judgement subtest so any advice would be much appreciated. Thanks

"Applicants are assessed based only on their raw scores (not percentiles) and all 5 sections of the test are taken into account."
However, there has been conflicting info about Monash's use of SJT. We also don't know how they'll use it.

I individually calculated the expected standard deviation using the 9 data points we have (1st-9th decile), and here's what I got:



I think using 2527 as the established mean and 297.269 as the standard deviation, averaged over 9 data points, would be our most accurate stab at a percentile calculator.

 

[dotwingz]

HAha i literally just did that


The issue is that they round up to nearest 10 so the s.d.s are slightly different so when i calculated based off the two scores it was slightly wrong. Your z scores are a little more precise so ill use ur S.D

we literally set it out the exact same omg

ETA: The mean is now: 2527 and sd is 297.269

Thanks. I couldn't find any information anywhere but it seems like its not very easy to find. It's a shame so many universities aren't more open about their admission criteria but no point stressing over it I suppose.

I would expect it to change, but its random whether it will go up or down. There are victorians still sitting the UCAT (unlike last year where everyone was done) so expect some changes.
