<p>When I was in undergrad, I could have graduated with a double major in three years with no summer classes, if I had really tried to, but I ultimately decided to do four years, mostly because I didn’t know what I wanted to do when I graduated. Looking back on it, it probably wouldn’t have mattered too much if I had graduated in three or four years, just do what feels right for you. I know several people who graduated in three years–some just powered through to get it over with, some came in with a lot of credits. I know one person who regretted it (mostly because she loaded up on her classes and took full loads during summer, so I think she burned herself out); everyone else seemed fine with it. Most of them are working or doing some sort of gap year before applying to grad/professional schools.</p>
<p>In my opinion, the biggest pro is saving cost of tuition. But keep in mind, that graduating a semester early vs. graduating a year early may not make that much of a difference cost-wise or time-wise if you have to a full load of summer courses. I generally recommend against taking summer classes if students can avoid it. In my experience, they tend not to be as high quality courses over the summer (too little time to really learn the material, they rush through things or skip things, the professors may be newer or lecturers rather than tenure-track professors, etc). If cost isn’t a huge issue (or if the cost of taking classes over the summer vs. taking the extra semester isn’t too significant), I’d recommend against the summer classes and just graduating a semester early.</p>
<p>If you’re asking if you should stay the full four years, it really just depends. There are some opportunities that are a lot more accessible as an undergraduate student, but there’s no reason you can’t make opportunities for yourself after graduation. You said you wanted to build your portfolio–would that be easier to do as an undergraduate or after college? I’m in the sciences, and I generally recommend that students try not to graduate early, just because it can often be easier to get research experience as an undergraduate, rather than after college. I don’t think I’m in your field, though, so I don’t know what building your profile entails necessarily, but if it could just as easily be accomplished after college, then sure, graduate early.</p>
<p>You could have a gap year after college to strengthen your application for grad school and for applying to schools–that way you wouldn’t have to apply while your still in school, which is a definite headache. I know students who graduated early and did research abroad or service programs or did a BS/MS program and got their master’s in that fourth year.</p>
<p>Could you perhaps study abroad for a longer period of time (a semester or even a year)? That might be a good use of your time since you said you wanted to travel.</p>
<p>If you’re only concerned about being 20 when you graduate–well, the emotional difference between 20 and 21 really isn’t that significant. I wouldn’t be too concerned about that. Any growing up you need to do can be done after college as easily as it can be done during college.</p>
