<p>Is is possible to take Orgo without having taken AP Chemistry? I would assume its not, but I was mailed one of the invitation letters to take it rather than the normal Chem class. It says right on the letter that you have to have achieved a 4 or a 5 on the exam, but I wasn’t sure why I would be mailed the letter if I wasn’t eligible? Orgo definitely sounds better, but I just wanted to know if I have any chance of taking it Thanks!</p>
