Re: ITT: Someone estimates your class rank.
Oh, my bad. I think I wasn't paying attention when I wrote that bit out. It's been a while since I thought about this stuff and I get sloppy occasionally. I made the spreadsheet a while back, though, so all the math on that part is still good.NYC Law wrote:I just ended up using NORMDIST to get the final rank, I figured thats what you were talking about since I was missing that last step.

Is there a way to convert gpa's from a 95 scale to a 4.0 scale?

Re: Class Rank Estimator
Maybe there is, but that shouldn't matter. Your 95 scale can be estimated as is. Just pretend the examples correspond with whatever works at your school. The math should work the same.shepdawg wrote:Is there a way to convert gpa's from a 95 scale to a 4.0 scale?

Anyone know a good method for obtaining an example data point? Or is this just something that is available via google for certain schools?

Re: Class Rank Estimator
Word of mouth for what determines honors, I would imagine. My school has a law review grade-on for the top 25 students in our class of ~370, and typically number 25 falls somewhere in the area of 3.7 (this is the common lore of the school, anyway), so we use 3.7 and 25/370 = top 6.8% as our data point.Hadlendale wrote:Anyone know a good method for obtaining an example data point?

Lol, looks some someone deleted the formulas.
Edit: Err, I think I fixed it. Someone who should check it though because I've mostly forgotten how to do this.

Re: Class Rank Estimator
We should ask YCrevolution to set up something that's not a shared spreadsheet. There's like 10 people in there fucking with it. Someone just changed one of the categories to "your balls."

alredy posted this in 1L Grade waiting thread, but wanted to get some thoughts in this thread, so sry for the double posting...
where are you guys getting the mean/median 1L GPA for your school? i found some info from NALP re: top X% and associated GPAs. however, that is for graduates and not 1L. thus, is this a good indicator of class rank or not really?

Re: Class Rank Estimator
The mean is what the courses curve to, and should be common knowledge at most schools. It'll do as a fill-in for the median, which is harder to get. Median at graduation and median as a 1L may or may not be the same, dependent upon whether or not the 1L classes are held to the same curve. At some schools I'm told that it drifts upwards.futurelawyer413 wrote:alredy posted this in 1L Grade waiting thread, but wanted to get some thoughts in this thread, so sry for the double posting...

Re: Class Rank Estimator
I'm not so good with math, but this seems to not work in determining class rank at my school. For example, my school gives A+ and all first year classes are curved between 3.0 and 3.3. Yet, using historical numbers, when I put an example gpa of 4.0, it gives a class rank of approximately top 6 percent. This simply cannot be. Heck, when I put the highest gpa in the class, it gives a percentile of top 3 percent. Can anyone explain how this math works?

Re: Class Rank Estimator
Here's a question: can you list the expected GPAs for the top 20 ranked students. Obviously this will be subject to a good amount of variance, but I'm curious as to how the top 5% is likely to shake out.
Assuming 400 students, Median is 3.177 (mean 3.2 (or slightly less) -- think 3.19-3.195)
10%=3.622
15%=3.511
20%=3.477
25%=3.410

Re: Class Rank Estimator
anyone know when class rankings typically come out? As in, how long after all final 1L grades are turned in do rankings come out typically for people?
Seriously? What are you waiting for?
