I know it was so confusing for me too...I finally ended up calling them, and the girl walked me through it...my problem is after I went to recertification it wouldnt go any further...I guess you have to make sure you have 20 CE hours, and at least 1 you check of the "pharmacy law" checkbox when you input it. Good luck!
You should be able to google online pharmacy tech CE and find a few reputable sites. The company I worked for offered everyone a free subscription to Pharmacy Technician's Letter, so I did all mine through that. If you have that option, it's nice and convenient! 👍
