INE’s DCACI Training

Hello all, I was asking for opinions on ACI about a month ago. My job has it from previous admins implementing it and nobody currently knows how to use it. Well, I got work to pay for INE for a year to help go for the DC CCNP and see their ACI is only 18.5 hours long. I guess I’m guess I’m used to CCNA where a course is 80-120 hours.

I’m just curious if anyone has ever used INE to pass the DCACI? It just feels like a very small amount of time to help pass a specialization. I also have the official book. Guess my question is, is 18.5 hours really enough content to pass this thing? Just feels very small to me.
