<p>The only opportunity you have to change your engineering major before freshman year of college is to submit a Program/Term Change request form before January 12, 2014. However, if you do so, you could be signing your own death warrant. The effect is that you would be relinguishing the admission you already have and then would be considered for admission with the regular admission group for CS, and thus you would again face the risk of being denied admission altogether.</p>
<p>The engineering college generally does not allow program changes between departments until after first year (you apply and then get a decision in second semester freshman year for a change to begin in sophomore year) but your desire to do so is something for which you could start the conversation when you meet with an advisor at summer registration. From a course viewpoint, not being able to change until after first year usually does not make much difference because engineering freshman take a lot of the same courses regardless of major. </p>
<p>Whether you will be able to change depends on circumstances at the time the decison is made. It is generally easier for an engineering major, rather than someone from one of the other UIUC colleges, to change to another engineering major as long as grades are decent. Neverthess, CS is currently an impacted major, meaning it is overcrowded, and if that remains true next year, you could face a risk of not being able to transfer even with very good first semester freshman year grades.</p>
