Cbs early decision near deadline (8oct) vs regular ??

[ArjunR555]

So CBS is one of my top choices... My dilemma is this... Do I apply ED near the deadline or regular D. How much will applying near 8 October help my chances vs applying RD. I will take cbs if I get in but I don't want to make that commitment if it's really not helping me and I can refine my app.

Thanks in advance for any replies
