<p>My Blue book tests are running out. How reliable do you think the Grubers tests are? I am trying to improve math mainly, so I think his explanations using his strategies might help a bit. </p>
<p>What do you think?</p>
<p>PR 11 tests. Seemed close to the real test to me.</p>
<p>Grubber’s CR passages is weird totally I think. I come to conclude the CR section is not reliable!</p>
