Luján L. - depends if you need a refresher or not. I'm thinking they will develop cohort 2 a bit more from what they did in cohort 1, but I'm not entirely sure what that looks like. I thought it was excellent, but I was not as far along as you are now with Clay. If they develop a more advanced GTM Engineering class using more than Clay (or with very advanced Clay usage - whatever that looks like), then probably worth it, but if you're comfortable using Clay every day then it might be just a refresher of what you already taught yourself. Do you feel comfortable enough getting any of Clay certifications? If yes, then probably too foundational a course. But then again, I don't know what cohort 2 will look like. Hope this helps!
