<p>I heard that the AP Chemistry exam has been changed this year. What are those changes?</p>
<p>In AP Chemistry, there is a type of question in which I need to write the correct net ion equations. Are there any ways for me to study those equations because I can only do the double-replacement reaction?</p>
<p>I think now you have to do all of the equations they give you (you don't have an option to pick which ones), and along with each equation they ask you a question. This is why many teachers believe that organic equations will be more hot this year, since more follow-up questions can be asked about organic equations.</p>
