Quick Question on APChem FR

<p>In case of the multi-step questions that require you to use part a to solve part b, and part b to solve c, etc. is it suggested that we use the rounded answer that we wrote down as the answer, or that we use the exact answer from our calculations?</p>

<p>I was skimming over the Princeton Review explanation for their free response questions, and it appears that the book is really inconsistent when it comes down to rounding so I got kinda confused :/</p>

<p>Any help is greatly appreciated! :)</p>

<p>I would use the answer that you wrote down for previous questions.
Even if you have the wrong value in the past sub questions, you won’t be penalized for USING that wrong value if you use it correctly in the next part(s). I’m guessing this applies to sig figs as well.</p>

<p>Yeah, if you need to use an answer later that you got wrong in a previous question, it won’t impact your point values for that. The grading for that type of question is usually “substitute and solve,” but it doesn’t say anything about getting the correct answer. A miscalculation will only penalize you once.</p>
