confused!

<p>i'm currently a junior, and i'm planning on applying to UIUC next year. i want to ultimately end up in the engineering program.</p>

<p>would it be easier to get in if i applied with undecided as my major and then switched to the school of engineering later on?</p>

<p>UIUC is ranked #1 in the country for materials science engineering which is what i want to do and i just don't want to get rejected...</p>
