<p>Pratt -> Trinity is as easy as checking a box. It’s so easy, in fact, that about 30% of Pratt students do it. (About the national avg for engineering students). You can transfer as early as the end of freshman year. Note that even if you’re in Trinity freshman year, you can enroll in any Pratt course you want. Same with the other way around. Most courses for Pratt students are in Trinity, in fact.</p>
<p>Trinity -> Pratt is a little harder, but if you plan for it and do decently in math/science courses, then it’s also just a matter of checking a box on a form. You just have to make sure you get the necessary requirements out of the way (EGR 53, math, etc. freshman yr). If you plan your courses accordingly and don’t fail, then they let you transfer.</p>
<p>If I were you, I think I’d apply to Trinity and plan on a physics major. Then, freshman year I’d take EGR 53 either first or second semester (which all engineers have to take) as well as EGR 10 (a half credit pass/fail seminar), and see if you like them. If so, then you can transfer. Since you’re on the physics curriculum, you should be taking chem and math freshman yr anyways, so you’d be okay in regards to engineering. EGR 53 is really the only necessary engineering course freshman year. Note that Pratt admissions is also more objective and predictable. So, if you have really high test scores, Pratt might be easier to get into. Alternatively, if you have lower test scores, applying to Trinity would probably give you a better chance of admission. That is a vast generalization, but there are more variables/uncertainties in Trinity’s admissions process. Not that I think you should base your decision on that (it should be on your interests), but thought I’d point that out.</p>
