Help with R Studio Class

Hello R Studio Community. I am currently enrolled in an R Studio class but am very very behind my peers. This is my first class and am pretty lost. I was wondering if there was anyone out there that could possibly help me out throughout the semester. Our professor has given us a file with data and exercises to do and every time I think I am getting somewhere something happens and my confidence then goes down.
TIA

So probably not really specific answers to very specific questions but lots of general advice & guidance
