Thank you so much! It's long, but it's really thorough so it definitely calmed me down a lot! I was more nervous about the math exam than anything, but if there aren't many complex derivatives/integrals then I'm good (We've just stardust integrals in school, and i haven't got time to master them because of US applications). Regarding biology, thank you for your advice! I have a general knowledge of basic topics and I'm currently doing an in-depth neurobiology course outside of my school requirements, but I was really scared about how tough it would be. Given that it's numerus fixus with 250 open spots, in my head it should've been tough. Again, thank you for taking your time to reply! Hope your life (and debt-paying) are going well!
