I know that what you get out of a club is what you put into it, but in general, would receiving top 8 winner (out of more than 160 competitors whom all placed top 4 in their own respective states) in ICDC in Accounting applications add any value to my apps. I also received 1st in that event in the regional and state level. I really enjoy DECA 
It is a significant achievement and will help your application quite a bit. It is not a big enough achievement to be “shoo in”,at many of the top schools. I know some ICDC placers who were turned down by Michigan (the school I am currently at), and there are schools out there with higher admissions standards.
What about schools like UCB or UCLA?
So overall, it does add value then?
UCB and UCLA are direct peers of Michigan, so likely a similar situation for both.
Does anyone else have any input?
anyone?
