<p>I noticed that the CB has undertaken steps to change and experimentally alter the previous exams for nearly every subject. Can someone tell me what changes will occur with these following subjects (if you know anything or better yet back up your sources from a CB link):</p>
<p>Biology
English Language & Composition
Chemistry
World History (?)
European History (?)
Pyschology
US Government & Politics (?)
Comparative Government</p>
