I am confused. Are you planning on double majoring in CS and some type of engineering, or do you mean you are considering majoring in either CS or some type of engineering? If you are considering a double major, you might want to consider that you will have to go to school more than 4 years.

Don't be discouraged if you haven't studied Calculus yet. People are saying you will have to deal with Differential Equations. You will, but keep in mind that you won't take that your first semester. You will start with a PreCalc or Calculus 1 class which will assume you haven't studied the subject previously.

By now you should have decided which school you will be attending. Talk to engineering faculty. Find out where you should be math-wise as an incoming engineering major. If you plan on taking PreCalc over the summer, make sure the school will accept the credit.

Also, see if you will just take general engineering courses your first year. That is what is done at my school. It allows you to transfer majors easily within the engineering department your first year. You may not have to choose between CS and engineering your first year.
