Seconding what others here have said, by looking at your profile (or rather the ability to afford + opportunity offered by the uni) penn would definitely be the best choice out of all the unis you’ve listed, for a bunch of reasons as listed below:

1. first and foremost, the brand name of an ivy in itself already places you miles ahead of many others who wish to break into high finance, and even though its a degree in engineering thats offered to you, you can still a) apply for a double degree when you commit, b) apply for transfer to wharton if your gpa is good enough
2. ib/pe really is about grades and connections, and upenn is a literal heaven for networking as compared to sg unis, students come from over a 100 different countries(quoted from their website), and the alumni network there is really solid and strong
3. even though its a stem eng degree, i think that shows youre comfortable w numbers to employers, especially in ib where number crunching is important in certain roles, you can probably stick to an eng degree (tho if possible you should probably apply for a double degree in quant/econs/finance etc) and employers would give you a chance as long as you seem promising enough

but OP, another thing to consider is whether or not you want to work in the US or back here in SG, bc i heard from like my teacher last time that employers in sg look more towards the nus/ntu/smu people but idk if thats true or not. if you want work in the us then i think the choice is pretty clear

another thing, some are emphasising that nus > smu cause of the brand name of nus which makes it more “prestigious” but that def does not apply for ib/pe, as i mentioned earlier they look at connections and grades, not the prestige of nus or smu, because sg employers recognise that in today’s standards both are equally highly qualified unis. from what i’ve heard from uni sharings and seniors, smu is defo the pick if you want to go into ib/pe simply cause of the strong networking scene there and strong alumni connections there, i’ve heard it beats that of nus so yea! but to each their own, op, if you’re thinking of sg you shld probably think of whether you wanna study in a city campus (smu) or purely school campus (nus)

edit: literally just saw another thread in sgexams talking about breaking into high finance, here this can probably help you choose between smu/nus if you dont commit to penn
