LOL, yep you certainly have my old apt!!! I totally forgot about the chirping sound. I believe that it is the smoke detectors; I never figured it out. You might need to change the battery or something. It never really bothered me that much so I didn't worry about it.
As far as OPP being easy, it will be if you really push yourself in the class the first two blocks. If you learn the principles taught during the first two blocks you will be set for the rest of the year, rest of next year, and for boards. It is the foundation of what you do. Those people who don't learn the first two blocks' material really well, will strugle for the next two years and be stuck memorizing everything for the exam and then forgetting it all; not to mention they won't be able to manipulate worth a crap. lol Anyway, Diana should hook all of the UAAO members up with a study guide I did last year I think. If you learn that material, there is no excuse not to get a high A on the exam.
Later!
