Deffered Adjudication

My question involves criminal law for the state of: texas ....Hi im austin hart. im 22 and live in Sugar Land TX. I recently got put on deferred adjudication for drug paraphernalia which is a class c misdemeanor. The conditions are fairly simple just 3 drug screenings. However the drug screenings falls on days I'm in class from 9-5 or work 9-5. Im simply here wondering if i can change my plea and pay the ticket off..yes i know it will be on my record but the career i am working towards is only concerned with felonies and isn't worried to much about misdemeanors. I was wondering if changing my plea so i can just pay it off and be done with it is possible and if so what is the process. I went to a justice of the peace court. I do not know if this helps or not i thought id share. If anyone has any info it would be greatly appreciated
