What is the safe amount of ECs to do while majoring in Engineering?

<p>I realize my Engineering GPA won’t be as good as I like it and even if it were. I still want to do more on campus because I just feel bored and that’s never a good feeling while going to college. I was thinking two academics,1 athletic, and another one just for fun. I want to do another one but thats why I’m asking this queston.</p>
