Yea, that actually is true. B+ is 3.5, C+ is 2.5, etc.
So I guess it needs to be recalculated. (I don't understand why they don't have minus grades. I would have much preferred A-'s over the two B+'s I received, if only for transfer purposes.
Yes for school GPA, no for LSAC GPA. From how I read their chart LSAC counts +/- grades as += +.3, -= -.3
True, but that doesn't matter for transferring. Any help figuring it out with the different numbers? I think it should be around a 2.8 for the first 2.9 for the second?
I'll do the first one for you, and maybe you can do the second; the steps are pretty straightforward.
First, you'll want to decide on a precise percentage who gets each grade. Even if you don't know exactly what they are, you want to pick one for the calculation. Probably the best thing to do (as was done above) is to just go right down the middle (take the average) of the two ends of the range. Thus if we know that 10%-15% get A's, we'll make that number 12.5%. Doing this for all of them in the first example yields
A 12.5%
B+ 22.5%
B 27.5%
C+ 22.5%
F-C 17.5%
A problem arises here though, because those numbers don't add up to 100%, but 102.5%. I will fix this at the end of my calculation because it's easier there. Since this problem doesn't exist with the second set of numbers you provided, you won't have to worry about that step.
Now, remember that 12.5% can be expressed in decimal form as .125. Similarly, 22.5% can be expressed as .225. We need to convert the percentages we have above to decimals so that we can multiply them by the value given for each letter grade. That looks like this.
A .125
B+ .225
B .275
C+ .225
F-C .175
Now all we have to do is multiply each of those numbers by the value assigned to each letter grade, and add those together. Thus we get:
A .125 x 4.0 = .5
B+ .225 x 3.5 = .7875
B .275 x 3.0 = .825
C+ .225 x 2.5 = .5625
F-C .175 x 1.5 = .2625
That last category, everything below a C+, doesn't have a specific number attached to it like the rest, so we sort of have to guess. I used 1.5, the value used above, but in reality it may be higher than 1.5 if Fs and Ds are very rare, and lower than 1.5 if Fs and Ds are common.
Finally, we just add all those numbers up and get 2.94 (rounded). That would be the average GPA given that curve, and is the end of the steps for the second set of numbers, but since we had a problem (mentioned above) with our numbers not adding up to 100%, we have to divide it by 1.025 (102.5%). This leaves us with
2.87 (rounded) for our average GPA.
