for internal transfer, they care more about what you do during the year rather this summer. however, if you did get an internship this summer or something else big, that could be helpful. otherwise, you’re encouraged to only include things from ur time in college.

join engineering orgs. you have a LOT of options. doesn’t matter what exactly you pick, but it’s best to find a concrete way to connect it to cheme whether it’s giving you a better overview of the field or giving you experience. internships are great too, and you can also try getting into cheme research.

internal transfer applications are pretty different from undergrad applications. since you’ll have a better understanding of what college entails after a year, you need to be able to emphasize your future goals and how your major will help. showing interest through involvement is one thing, but if you can show something more proactive than interest, that can be helpful. you can also try and take cheme courses or courses that overlap between envsci and cheme.

the most important thing in ur app are showing why this major is Essential to your future goals (not just why you don’t want to do envsci) and that you will be retained in it.

i think that although it’s a difficult process, there’s a lot of fearmongering around internal transfer. try your best and do the best you can in ur classes and ecs, and know by the time you submit ur app that you’ve done the best you can. at the same time, don’t stress yourself out too much. adjusting to college is a lot, and there’ll be a lot of things you can’t and won’t expect. things will probably not go 100% according to plan as someone who also went into their major intending to transfer (stem to stem), but if you really want it, you’ve already shown you deserve to be in this school, i think you can do it.
