In a word: hard. Intel is one of the more selective designators...I'm not completely sure of BDCP rules, but I don't think you can redesignate while enrolled.
Another question: if you're a sophomore in a non-tech major, how can you be in BDCP at all? The limit is 24 months from graduation...unless you're graduating a semester early?
Im not really sure, it was an issue at first but they let it go through anyways. Also you can redesignate, but you are really just reapplying for the program. When it goes to board they know you are alraedy in, and then they will try to move you, is what i was told before i signed my papers!!!
