Not really. It's meant to separate the good from the great. It's nice to be able to get everything right, it's better to get everything right in a fast time.I understand that but time restrictions neglect plus incorrect answers taking away from the score puts too much emphasis on being able to answer correctly as soon as you look at the problem. Take my math score on my PSAT for example, it's my lowest one, but my math score on MCAS was my highest. Both are time restricted tests but on MCAS I didn't have one minute per question as with SAT. When I have so many minutes to write an essay and answer other prompts and the article I have to read takes a large amount of the time even when skimmed through it gets ridiculous. I have no problem writing an essay short and sweet in getting to the point but that takes time to think about.
I agree, being allowed an hour to answer a dozen questions is overkill but only being allowed a 25 minutes to answer 25 questions and read/analyze an article is overkill in a negative way.
