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.

Am I missing something?

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