<p>Hey CCers,</p>
<p>So I was going through some practice tests when I came across questions that didn't have a correct answer or had the wrong answer as marked right. (I'm not BSing here, one was "find the angle measure of z+x when z+ x were alternate exterior angles on a transversal, so it's obviously 180 and another- I checked it with CC and the internet and solved it myself and the collegeboard answer was just wrong. )</p>
<p>I even had my dad (engineer) and my dad's friend (a math prof!) look it over and they both said the answers were wrong.</p>
<p>Do I just have messed up tests or something? Or is this actually pretty common? (It was the 10-11 practice test and some tests a kid gave me from the official course). </p>
<p>Thanks! I just thought it was really weird.</p>
