<p>How does partial points work in AP Chemistry exam?</p>
<p>I know in Stats, if you get the answer to part A wrong, but you maintain consistency and keep using the proper formulas, you still get the preceding questions correct, but not the question you initially missed.</p>
<p>But in Chemistry, let's say I didn't use the correct value, but my proceeding steps are correct in what formulas they use.</p>
<p>Do I get the whole chain of problems wrong or just the initial one where I had calculated the incorrect value?</p>
<p>And do we get partial points for any of each letter? Like say if it was Delta WFRAAGER (something random, representing something) was +100000000 kj/mol, but I had put -100000000 kj/mol. Do I get half credit or anything for the part of the letter?</p>
