Yeah it’s a cert shop. Not worth it imo. There are people in the industry who are in the weeds of things daily and I’ve almost never seen or heard of any of the people who retire for that publication. It’s as if they are just freelance writers. The info is not impressive - maybe helpful to beginners but certainly doesn’t contain anything worth that much. Honestly, I think it’s just a cert shop to wave around and say look I got this. And employers probably buy that 💩
