3 (24/30) x 75 =180
4 (20/30) x 75 =200
A school that places more value on one metric over the other would use a factor greater than 1. An example is the SA formula, where science gpa plays a dominant role.
San Antonio Formula [science GPA x DAT AA Score/30 x 4 +overall GPA] x 50 = Overall Score
I get where you're coming from mathematically, but I'd still disagree that placing more value over one metric is exclusive for said system. That and I'm not sure what the 3 (24/30)x75=180 and 4(20/30)x75 is referring to...That seems to be the formula: (sci gpa+ogpa)/2x(DAT/30)x75? That's not derivative of UNLV's formula. The gpa needs to be divided by the total and the DAT contribution (the (X/30)) needs to be
squared (assuming an equal score spread). The final total of either of those scenarios should only have a max value of 75 (as in a perfect scenario, 4.0GPA and 30DAT, the student's formula would look like 1*1*1*75=75)
For the example I specified:
Formula: (cum gpa+sci gpa)/8 * RC/30 * (OCHEM+QR+BIO)/90 = (a total up to 75)
3.0 Student with 24s: (3+3)/8 * (24/30) * (72/90) * 75=
36
4.0 Student with 20s: (4+4)/8 * (20/30) * (60/90) * 75=
33.33
UNLV makes two of the three variables in a x*y*z perspective reliant on performance on certain sections of the DAT. Doing poorly(overall) on the DAT will affect an applicant far more severely than having a poor GPA. And likewise, doing exceptionally on the DAT(overall&especially reading comprehension) will benefit an applicant more than having an exceptional GPA. The fact that
two out of three of these variables (which are multiplied and have a max value of 1) are thus reliant on portions of the DAT already demonstrates how the DAT is valued more than GPA in my honest opinion.
Now I don't really have a wish to hijack this thread to go on a mathematical tangent, so I'd just like to leave it as I'd disagree mathematically with Doc Tootache, but I still respect his analysis on the matter. Take my explanation/insight as you will OP.
Back to OP:
OP your pre-interview score would be close to: (3.49+3.15)/8 * (20/30) * (29+22+20)/90 * 75=32.7
As you have the potential to score 57.7 (competitive is 50-55+),
it is likely you would be invited to interview if you applied. However, from my personal experience,
it is extremely important to have a pre-Dec or pre-Jan interview with UNLV, so apply soon if you plan to.
