Nursing student improving my knowledge

Hi there :)

I wanted to ask for any advice on what content to focus on from general chem heading into orgo chem.

I‘m a nursing student and wanted to brush up on my knowledge of organic chemistry because I think it’s fascinating! It’s not relevant to my degree! I last took chem in high school, and my uni does not have chem I as a pre-req for orgo.

Thank you :<)
