Hi!
At the risk of looking stupid, I think I found an error in the Answer Key for October 2020.
The answer key for Section 3 Question 12 says A–I think it should be C.
In the original equation if t=2 for 2 hours then y = 200. Then if you switch to minutes m=120 your exponent needs to be 120/60 (or m/60) to get the same y=200.
Thanks for catching the mistake. I just checked the video and while my explanation is correct, at the end I incorrectly said the correct answer is A instead of choice C, which is the correct answer. I will make the correction.
I just went through the reading/writing language sections of this October 2020 and it is loaded with numerous typos – both within the passages and in the questions. Is it possible this is a rough draft of the test?
I have not checked the reading/writing section of the test and it is entirely possible that there are typos in the test. As you know Collegeboard no longer releases a hard copy of the original test, and most folks are now copying the content from the online QAS, and this process is prone to errors. I did check the math section thoroughly, and there are no errors in that.
I tutor in those sections and you are correct. This test had several questions that had grammatical errors and incorrect spelling in lines of the passages and in one or two prompts.

Am I missing something?

Dabral – Just to clarify – is the correct answer for S:3 #12 – “C”? The answer key says “A”.
