<p>hmmm… I’d say kinetics or buffers were the hardest for me. One thing I’d say though is that lab time is really essential for AP chem. I know you’re self studying it, but if there is any way you can get the lab time to perform some labs, perhaps a titration or identifying ion lab, it will really help. Maybe talk to your school chem teacher. I know for me, being in the lab so much helped me with predicting reactants and just understanding the material in general. I really cannot over stress the importance of lab work and applying the calculations you learn from the book to your own data. </p>
<p>Also, as for what you have to memorize, you should know the basic cations and anions and their basic colors (if they have one). You should also know some of the products in common redox reactions, especially those with Mn. Also, make sure you memorize the weak and strong acids and bases as well as the different shapes and bond-angles of molecules.</p>
<p>Here are the links to two very good pages with stuff that if you memorize before the test, it will be a lot easier. It helped me get a 5:</p>

<p>I hope that helped and good luck! Chemistry is awesome!</p>
