Best way to study for RIBO Level 1? Are Dino YouTube videos enough?

Hey everyone,
I’m currently preparing for the RIBO Level 1 Exam and wanted some honest advice from people who’ve already taken it.
What’s the best way to study for this exam? There seems to be a lot of material out there (IBAO books, practice tests, etc.), and I’m trying not to overwhelm myself.
I’ve come across Dino’s YouTube videos and was thinking of just subscribing and using that as my main study source. For those who’ve used it:
Is it enough to pass on its own?

Or should I still get the official IBAO study material?

Also, how important are practice exams compared to just watching/reading content?
Would really appreciate any tips, study strategies, or things you wish you knew before taking the exam!
Thanks 🙏
