I've worked as a tech for two months now in retail and will be changing to an intern as soon as I get my license when classes begin. Interns at my store do a majority of the data entry, double checking SIGs/scripts and patient counseling. They rarely do any of the other tech work (filling, ringing out, etc).
At least in your situation, you probably know a lot of the drug names and their classes, generic versions, etc. I won't learn much about any of that until the end of P1, so even after I become an intern, I'll still be mostly useless until the end of P2. Everyone is until they learn the basics and become familiar with that companies prescription programs.
