Does this AP Chemistry curve sound accurate?

It says if you scored 20 or more on the mc questions, you’ll most likely get a 3 or better. If you scored 28, you get a 4 or better. And if you scored 40 on mc, then a 5. Now it says this is only for the multiple choice, because it is only 50% of your grade.

So does this sound accurate? I have used the the AP calculator (2008 released exam) and it seems to be way harsher. I know this is a new format for AP chemistry, so is it accurate?

Old exam had 75 MCQ

@bloodythunder , I know, I’m talking about the new one, that has 60.

That curve looks easier than the new one.
