164 Score in Quant with 4 mistakes?

GRE General
1

So I took the Powerprep test today. I had one mistake in the first section and 3 mistakes in the second section. I got 164. WTF. Why?

2

The PowerPrep scoring algorithm is less forgiving than the actual thing. Don’t worry.

3

Oh Okay. What Score might I get if I have 4 mistakes? (1 in first section, 3 in second section).

I am not privy to ETS’s scoring algorithm my man. I cannot even make a calculated guess here.
