Is my biochemistry just using jargon or am I seriously underprepared as a transfer student?

I’m a transfer biochemistry major at UCSD. I know the prior knowledge needed for the class because the criteria to even apply to UCSD is to complete all the pre-requisite classes and pass them, but I feel like I’m lapped in my education and information. Like today in my biochemistry class, we were going over hydrogen bonds, orbitals, functional groups, entropy and enthalpy, etc. I know these concepts because I went over it at my community college. But my professor kept on going into so much depth and technicality and I was so lost. Microstates, first hydrogen sphere, clusters, hydrophobic core, dielectric constant, and Tanford’s Transfer. Am I genuinely supposed to know all these terms before taking a biochemistry class or is my professor just throwing around jargon or concepts that will be explored more in biochemistry as a whole? If it’s the former, I might consider dropping and doing a whole overhaul of content review.
