What does Optometry require? Some can say intelligence, dedication, motivation etc. These things are not really talents but acquired traits. Optometrists and doctors aren't special people folks.
You are right, these are acquired traits for the most part. No one really expects someone to enter college and shine from the start. However, is it too much to ask that after 4 years of college, a student interested in ANY health profession should have at least a fairly good grasp on these traits?
Yes, people have a few bad semesters/quarters, and not just in freshman year either. These 'dry spells' may or may not be your fault, but they are your responsibility. As someone who has had them from time to time, I can say with a fair amount of certainty that they (alone) probably wouldn't cause one's GPA to slip below a 3.0, assuming decent performance during the 'good' times.
And finally, of course most people are theoretically capable of most things (except those tasks limited by physical restraint maybe). However, you also have to consider the effort put in vs. the payoff in a non-emotional way.
Example: I might
like the idea of building airplanes and space ships, but my grasp on math isn't exactly an iron fist, and I would most likely struggle horribly in engineering classes, for something that was more of a passing interest than anything else. A hyperbolic example I know, but hopefully the point is apparent.
Is a person with a 2.8 gpa more likely to fail Optometry school than someone who earned a 3.0? Maybe, however they are both B averages on paper, and if someone with a higher b average can do well than so can someone with a lower b average.
Well, the difference between a 2.8 and a 3.0 is slim, and I agree, sort of arbitrary. However, its a slippery slope...
If a 0.2 difference is no big deal, then a 0.3 difference isn't much different either, right? Once that is established, what about a 0.4 difference? Hell, why not just make it a nice 'round' number and say 0.5? By then, you are looking at someone with a GPA of a 2.7, and viewing them on the same level as someone who managed to get a 3.2. That
is a pretty sizable difference in my opinion. You gotta draw the line somewhere, right?
