<p>I was just working through some of the questions, and there was a couple i just didn't know. they are question #6 on 2001, #5 on 2000, and #5 on 1999. if anyone has the answer to any of these question, It would be greatly appreciated. Also, in our class we did very few labs, so i'm having trouble with the lab questions on the free response, does anyone know any website that would provide some information on lab that's usually done in a Cham Ap class?</p>
<p><a href="http://www.collegeboard.com/ap/pdf/chemistry_01.pdf%5B/url%5D">http://www.collegeboard.com/ap/pdf/chemistry_01.pdf</a> 2001 free response is here, if any of you care to help</p>
<p>Sign up for an account on <a href="http://www.apcentral.collegeboard.com%5B/url%5D">www.apcentral.collegeboard.com</a> since they have the detailed worked out solutions with scoring guidelines for you to use. Although it's reserved for educators, must students who self study just sign up for one so it's no big deal. If you having trouble on the lab questions then a guidebook will be of big help and this website (I think) <a href="http://www.adriandingleschemistrypages.com/ap.html%5B/url%5D">http://www.adriandingleschemistrypages.com/ap.html</a>. Also look under the self study thread for more AP chem websites.</p>
<p>It's not a website, but Cliffs is supposed to be a good resource for lab info. I know it's NOT generally recommended for AP Chem (most recco PR), but I've heard it covers the labs in quite a bit of detail. It's just supposed to be lousy on everything else.</p>
<p>Also, if you have specific questions about any of the free response, post it here - I'm willing to help explain them.</p>
<p>make sure you know solubility rules; those are so key for the lab questions</p>
