pharm tech is a certification, not a degree.
it depends how well you are able to study. there's not way for anyone to know how long it would take you to study for the pharm tech certification exam. 1-2 months should be enough.
although research experience doesn't have anything to do with being a clerk or a tech, experience does help, and as a clerk/tech, they will train you and help you through it. you just need to first get your foot in the door.
