<p>Hey just wondering if i put that i am going to apply early decision on the pre application data sheet can i still change my mind on the common app? Just in case i change my mind thats all.</p>
<p>Sure. If you chamge your mind, I would recommend an email letting them know.</p>
<p>On the other hand, it sounds like you are not sure, so you might be better indicating RD now, and then if you decide to apply ED you will appear to be increasing your interest as opposed to the other direction. The pre-app is just to get your file opened and has no real impact, so only put ED if you are sure.</p>
