Lina's Final Project

I'm changing my project topic from "Extrema, Optimization and Concavity" to "Trigonometric Techniques of Integration", so if anyone wants my former topic, he or she may do his or her project on it. Also, sir, if I'm not mistaken, you said we were going to cover the new topic I chose after the AP test. Therefore, do I need to have my project done earlier or do I still have until May 18 to hand it in?
