Do I need to know Magento already?

It helps but isn’t required. The course is structured so a non-Magento dev can follow along (we explain Magento concepts as they appear), but a Magento background lets you skip ~25% of the foundational explanation. If you’re a designer or solo founder with zero Magento, the cohort track is the right pick, the live calls give you space to ask “what is a plugin?” without slowing the whole class. If you’re a Magento veteran, the self-paced track is fastest, you’ll be done in 2 weekends.
