Honestly, I own BR Orgo 2003, and this one even has a lot more than you need. I think that given the possibility of Orgo not showing up in your exam much (of course, this doesn't mean you should neglect it as this will backfire on you), buying a new BR set is useless.
BR Orgo is extremely dense, which, if you are good at Orgo, is unnecessary. I am using EK Orgo, and supplementing it with TPR and EK 1001. I'll do some passages out of the old one, but I don't think it's that big deal. I wouldn't buy it unless you have extra money laying around the house. 😎
