Manhattan prep test score doesn't make sense to me

[ZzzGre]

Hi, 

I took two prep exams on Manhattan and i was surprised when i saw the quant results.

Out of the 40 questions i had only 2 wrong and i got a result of 166, i thought it would be higher. In the second test, i had 4 wrong and i got 64.

Is this normal? Should i expect the same in the real exam? it's really frustrating if true.

 

Thank you in advance for your help.
