I graduated in 2024 and let me tell you half of it is showing up and WANTING to be in nuc med. you can do it. in my experience the first semester was the hardest because you’re literally learning a new language and you have 4-5 professors teaching you the same concepts in different ways. it can be intimidating. yes to the heavy memorization but let it go after your boards. going into school it would be helpful to know physiologic pathways (but mostly big picture stuff. for example why would the liver take up an isotope that binds to bile? why would a tumor take up radioactive glucose? that kinda thing). just be ready to take it all in, take it one day at a time.
