So I have a couple years before I go off to university but I'm picking subjects to study right now. I'd like to do phys/chem/maths but I feel like I should have bio in case I decide to go for med. However, I'm trying to convince myself that it's pointless but an answer to this question might help. I'm interested in studying aerospace engineering but a guy I was speaking too convinced me that their aren't many jobs available and being not from the US, I wouldn't be able to get a job (say in defense-though really I want to be sending probes to other worlds). Anyways, mechanical seems safer but I don't want to give up my dreams that easily. Is it possible to do both Aerospace and Mechanical at the same time? That same guy convinced me that I'd need to be Einstein in order to not crumble under the pressure. Is this true? Thanks, I'd gladly give more information if anyone's curious.
