<p>I am going into mechanical engineering at Cal Poly SLO next year. How many credits should i take since its a difficult major? Any advice?</p>
<p>Start with the basics. Re-take any classes that you're concerned that you might not have gotten a firm grasp on in high school, even if you can place out of them... It's necessary to have a solid foundation at the outset because it's impossible to make up a solid foundation as you go along.</p>
<p>Ease into it... If there are any non-engineering requirements, take one or two of those. Take what you're comfortable with!</p>
