Working while in school

Hello,

So I am currently in an 18 month fast paced program. I forsee that I probably will have to switch jobs once I get into the actual Surg. tech courses, I am taking pre-requisites right now. But that actually may start in about 3 months, I thought I had longer, but I don't. I have to go to work while in school unfortunately. And I only have a CNA certificate right now. Are there any jobs I could do while in school that are relevant to this line of work? I want more exposure to the OR... but also know I am new to the field. Any advice is much appreciated! Thanks!
