<p>I can’t remember what was tested on the last six questions of the science section on the Oct ACT, but I remember at the time thinking I should brush up on it. Does anyone remember what the scientific concept was in the last six questions? Thanks.</p>
<p>By the way, other than organic chemistry and chemical equations(which was used in a red book practice test) has any other type of scientific application appeared as essentially the basis of passage where knowledge of the application would clearly help? Thanks.</p>
