OK, if you're going to do fancy, we can make this better. It's been way too long since I've done programming or web development, but if I lay out the algebra, could you program the tool to accept any two data points (i.e. "top 10% = 3.___ and top 15% = 3.____") instead of requiring one data point and the mean? Over the years I've cranked a lot of requests that didn't have the mean.

In order to do it we'd need a function that returned the Z-score for a given percentile, but I believe that has to already be baked in somewhere even if you are given the median?

if you give me the equations I should be able to make it work... I don't really understand what's going on with the statistics, I just looked up the equations for the excel functions and put them into code, and it returns the same output as the spreadsheet. unfortunately that level of knowledge doesn't allow me to do much but take what you give me and put it into code.

This may sound stupid, but how the hell am I supposed to enter a "known" GPA and percentile if nobody has their grades back?

you can try and find last years rankings they should be close

Yeah. The formula for Z score for a given percentile is:

=NORMSINV(1-(A1/100))

where A1 = top whatever percentile, e.g. a 3.7 at UVA would enter 6.8.


The other formula I'm using to drive the estimator is called "NORM.DIST" and it requires the mean for estimation. There might be an Excel formula to calculate the mean given a ranked data point or two, but I need a bit of time to think on it.

Aww yis. I'm busy now but will algebra this to pieces the next time I have a moment.

The quartiles are:

25%: 3.619
33%: 3.524
50%: 3.309
75%: 2.953

My GPA is 3.786

Thank you in advance

About top 15%. Nice work with the GPA!

Anyone have any recent GULC data points?

No data points....Curve is 3.0 and my GPA is 3.2....Any idea how to calculate/get a rough estimate?

Trying to figure out my graduation ranking.

179 = top 22.8%
180.5 = top 7.9%

My GPA = 181.25

Thanks for the help.

Thanks for the help.

So, this is totally winging it, but I plugged in 179/22.8% and then kept inputting means to find the percentile for a GPA of 180.5 until it came out to about 8%. This happened with a mean GPA of 177.3, so I'm assuming that's somewhere around Chicago's mean.

If you plug in your GPA with the 177.3 as the mean, that puts you at about top 4%.

ETA: I also added this estimating ability to the calculator on my website... no guarantees of accuracy, though. The only school I know of with a unique GPA range is UChicago, so I added a checkbox that you need to click if you're estimating a UChicago GPA. (If you go to a school that has a weird GPA besides UChicago and you need to use that feature because you don't know the median GPA, let me know and I'll add you in.)

I can give you top 33, 15, 10%

But they don't release the mean, for whatever stupid reason.

If anyone can figure this out without the mean, I would be appreciative:

Top 33: 3.43
Top 15: 3.62
Top 10: 3.70
My GPA: 3.39

Sounds about right to me. Thanks for your help!!

Class rank indicator doesn't seem to be working. Says page temporarily moved but doesn't redirect anywhere.

Is it still not working? I was switching servers right around the time of your post and that may have contributed to it. If it's not working I would recommend clearing your cache/trying a different browser. (Sorry for the trouble! The old server was being pesky and I wanted to investigate without risking the stability of my sites...)

Would love some help trying to figure out this model.

top 15% 3.590
top 20% 3.548
top 25% 3.483
top 30% 3.421
top 35% 3.379

My grade: 3.673

Any advice from anyone on how to do this?

"known percentile" means a lot of school publish things like "top X% of the class [historically] requires Y GPA" - coupled with information like "median GPA is Z" you can calculate fairly accurate class ranks assuming a normal distribution.

How you actually get that data is entirely school dependant and TLS can't really help. It will be in materials you received, on private school web interfaces, emailed to the class, posted in the library, whatever.

Can someone run mine please?

Top 10%: 3.61 
Top 25%: 3.36 
Top 33%: 3.28 
Top 50%: 3.07 
Top 75%: 2.79 

My GPA 3.88

redid the estimator a little bit, should now estimate medians more accurately and is a bit easier to understand, also added dailygrind to the credits page for doing the equation stuff

Is there a way to find out what the median GPA is at your school if your school doesn't release rankings? I know that for individual 1L classes, the median is set to 3.3, and for upper-level courses, 3.5. But I am curious to know the median cumulative GPA.

this is probably a dumb question and answered previously (didn't go through 4 pgs) but how do we know what the rank of a set gpa is when the law school goes off a range from 0-5% for a 4.3? I would think it highly unlikely for the school's distribution to be such that 5% of ppl got 4.3's
