Your breakout of the GPA scoring is quite helpful.... I had never seen it broken out before. After what you wrote, I now know that all the degrees become factored into the GPA calculation. I think you misunderstand me though. What I wrote was not intending for applicants to compare themselves against themselves but, rather, their competition. Based on what you wrote, it is still true that someone's 3.5 in a Masters degree will still have more weight than someone's 3.8 in a Bachelor's degree (all other factors about the degrees aside) simply because anyone with a Masters must already have the weight of the Bachelor's points as well to be factored in. I only went into detail with it because I have heard (mostly off this forum but also on it) those with advanced degrees worrying about the GPA calculation. Their concern is "Well, if the board just sees my GPA as a number in a calculation (before looking at the actual application) then wouldn't someone who has a 4.0 (even though in an undergraduate degree) look better if it's just a number that the board sees??" Addressing this concern is why I viewed it as important for the forum to discuss it more in depth.
And you are right about a board member looking unfavorably on someone whose undergraduate GPA was significantly lower than their graduate one. Anyone who has been to graduate school would agree wholeheartedly with you. In fact, as strict as many graduate programs are for getting in, many are far stricter about allowing you to stay in. They pick you because they expect you to perform at high levels, and if you don't.....well, they will quickly get rid of you. My graduate school had a policy that if you got below an 80% in more than one of the core courses of the program, then you had failed the program. (I knew of one girl who had a grade come in late and was actually pulled from the commencement lineup the day before.) This is why most graduate schools do not have a bell curve for grading. They expect only the highest performers to be there. I cannot speak for the medical and law fields though. I have an idea that their's might function differently....It still would depend on the situation of the two degrees for that person though. If I had a 4.0 in a Bachelors degree in Underwater Basket Weaving or Theater or such and then later when on to earn a Master of Science in Mathematics with a 3.5 GPA, I would expect any board member to look far more favorably on my Masters degree even though while quite good was still considerably lower than the B.A. GPA. (I did not do either of these degrees, for the record.....lol.....though I must say, while I learned quite a deal from all the electives I took, my undergraduate degree was kind of lame......I truly wish that I had tried to challenge myself more and not have waited until grad school to "kick it up a notch".....but I was a teacher for several years before I enlisted, and the experience definitely helped me in advising my students in how to approach their degree/studies decisions.)
