I'm a college student working on to be an RN. I need a side job and pharmacy tech seems pretty interesting. I live in CA and I'm not sure about pharmacy tech laws here. I just want to know what's the difference between a licensed tech and a certified tech? Also, I plan on taking the PTCE w/out taking classes because they're expensive, I'd rather study on my own. Also, if I pass the test, am I licensed or certified?
