<p>On every Sat math test I usually get all the hard questions right but I get some medium wrong. If I have enough mathematical ability to do the hard ones, it should mean I can do the medium ones too. Can anyone relate ?</p>
<p>Hard questions aren't necessarily "hard." It only means that a larger percentage of students got that question wrong than other questions. Maybe your training has just been different than others, and you are better at certain concepts. </p>
<p>You might want to check over your answers on medium questions. You might have just made a stupid mistake or fell into one of the ETS' traps.</p>
<p>Hard questions come in two varieties: </p>
<ul>
<li><p>Hard content: these problems are straightforward but require specialized math knowledge. For some reason, these trip up a large % of people</p></li>
<li><p>Hard reasoning: these really require some fairly insightful thinking. Much less common than the above.</p></li>
</ul>
