<p>My S took 5 yrs, that included a year of co-op. He double majored with a minor. Some summers he took classes and took a few classes when he was in co-op. Had he not done the co-op or taken summer classes he would have finished in 4 yrs with 1 major. Lots of his friends in engineering finished in 4 as well as friends in math, physics. To graduate in 4 yrs is very possible, but you can’t change your major or do co-op or drop a lot of classes.</p>
