Any tips for a computer science and engineering student?

<p>Hi I will be a new computer science and engineering student and am wondering what tips current student would give to me regarding my major??? IS computer science hard like the classes?? How much programming experience do I need beforehand to do well in computer science? Also what are the required secondary classes for it? Its jjust calculus and physics andd no chem required right?? I already have Math 2A-2B with AP credit and hope to place in physics 7C</p>
