Practical will help you mroe.
You can always "study" names and classifications yourself in your own time if you want.
You need to find out what a second semester internship would involve. If it's just a repeat then do the study as well. IF it really expands practical experience and will invovle you acquiring the terminology in the real world then go for it.
KNowing the name of something without understanding it's relevance isn't as good as knowing the name AND it's relevance. Finally if the terminology is always clear in usage then why learn it ??
BUT ... the best thing you can do is to call the different colleges you woudl like to attend in the future, and ask those in the dperatment you woudl want to study in what THEY woudl recommend and why !!!!
Good luck with whichever route you chose
