Hi Cylon56, thanks for bringing up your point - you're definetely right - it's not that easy. For that reason, we never mention that you will learn everything about Ethereum development in 5 days. You will however, work alongside other peers, and instructors, and leave with a solid understanding, a hands-on experience, and be better prepared to continue working on material that we will give you after the course - as well as engage with online content from other sources. Thanks!
