I'm fairly sure that some of the questions in this practice exam are actually wrong. or at least misleading.

I'll keep looking when I actually get to work and post my score later I think

I got 88% (it's been a long time since I studied electronics).

as I said, I think that some of the questions are a little misleading.
one of them I know for sure that the answer that they give is wrong.
