What I meant about my other post is that colleges know that students often change their major. There really isn't a benefit of declaring a major right away. Freshman year is full of general ed courses anyway that it won't really matter. I know when I was in college the only major that really needed to be on an exact schedule right away was nursing but even then there was some leeway freshman year. Schools don't really look at your declared major when you apply because they KNOW they will be changed at least once. I think you are worrying over nothing is what I am saying. If he wants to put something down, fine, if not, undeclared is perfectly fine.
