I take the controversial position that the "I'm a poor test-taker" argument is a copout. Unless someone has a learning disability, they aren't poor test takers, they just don't want to study. It is true that some people learn more quickly than others, but the slower learners need to just buckle down and accept that they may have to study a bit more. The objective is to learn. The test only exists to confirm that learning has occurred.
I’ve often thought that those people who claim to be “bad at taking tests” are probably more likely “bad at knowing how to study”. I mean, any results of anything are tied to the process. If the results are not as desired, the process needs to change. This is not a personal attack or an insult. Many, many people do not know the optimum way to study for tests.
Also, if there are “bad” test takers, then obviously there must be good test takers. For me, I always do very well on tests. Is this because I’m a good test taker, or is it because I work really hard to prepare? If you say it’s because I’m a good test taker, then it devalues the importance of studying. Whereas on the other hand, if you say it’s due to my studying, then it follows that “bad” test takers fail due to ineffective studying - meaning the idea of “good” and “bad” test takers is irrelevant.
But as always, like with anything else, it’s essentially impossible to understand what it’s really like for the opposite side, since in this case it really is impossible to “walk a mile in their shoes”. So I accept that I have a bias, as a “good tester”.
Regarding the shortening of the time frames, I’ve always thought that they were excessively long anyway. I have to believe that almost nobody takes the entire time, and if they do, they really didn’t know the material anyway. I’m willing to be proven wrong, but the shortened time frames seem completely reasonable to me.
