<ol>
<li>Grammar</li>
<li>Very little vocab used</li>
<li>Includes Trig (sin,cos,ect)</li>
<li>Science Section (basically reading and interpreting data)</li>
<li>Score Choice ( can pick which score to send)</li>
<li>Optional writing test</li>
<li>No penalty for guessing (this means you should answer every question)</li>
</ol>
<p>Also, the ACT questions are generally less tricky than SAT, but there's more of them and you are given far less time.</p>
<p>ACT is more an achievement test. ACT is out of 36. SAT is out of 2400. ACT is almost exclusively used in the midwest, SAT is everywhere. ACT tests english (grammar), science (interprepting graphs and tables mostly), reading (comprehension of passages), writing (essay showing development and focus) and math (a few algebra 2 things, but it depends on what math classes you've take covered). SAT has an essay with the same focus basically, it has a math section which is less straightforward and more trickier, but not harder. the critical reading is about reading comprehension, involving more terms than the act, and the writing mc is about grammar and selecting the right word</p>
