<p>I'm thinking either bioengineering or computer science (something mainstream =/) but are there advantages to going " undeclared?" I know for some they have a planned "resume" that follows their career path and even some colleges force you to pick a major. If you had a choice however, is it better to go undeclared and THEN transfer in or pick right now? Schools im considering for this option are the UC's, particularly LA and Cal.</p>
