Chemistry

I took the practice test on the Collegeboard website and got 21/27 answering every question; can someone equate that to a scaled score out of 800 please!

It doesn’t work that way. You can’t convert it.

So how does it work @DarkEclipse

It doesn’t work any alternative way.
You have to give the a test with the actual amount of questions (85). You can convert your score from that.

@DarkEclipse well can you tell me how many I can get wrong and still get a 780+? Assuming I answer every question

You can get 6 wrong and get a 780.
