<p>Anyone use the AP Biology Campbell book (8th edition preferably)? Do you use the accompanying online source which has practice tests and reading guides for the chapters?
Like this: Biology</a> 8e AP* Edition - Log In</p>
<p>If so- do you still have access to a lot of the videos and practice tests for the chapters? My AP Bio class for some reason lost access to it and our teacher doesn't know why either.</p>
