Pearson Vue Trick- how accurate?

Okay I just took my boards this morning and I am curious to know how accurate that is?

I am not getting the "good pop up"

I got 75 questions- approx 10 SATA, 3 EKG strips, a few exhibit questions and the remainder a mix of medications and priority.

I did NOT get any dosage calculation.

I didn't think the questions I got were that difficult and felt good about it until the "trick" let me down... any comments???
