<p>I would say that since you can compare your stats to your brother’s and they are “no better” (grades worse) that your likelihood of acceptance is not as good as his was. That said, if you are really in love with Brown and can make the case for why you are the right fit for Brown and vice versa in your essay (which will carry far more weight than the interview BTW) then do go ahead and apply. (It would be far worse not to and always wonder?) I would do what you can to strengthen your position, including ?retake SATs? and very likely apply reg app and do everything you can to get great /better grades this coming semester. Best of luck, and pick some great other schools that you will love just as much so you have lots of options!</p>
