Nobody Told Me About IT
Nabil Gharbieh has a certification problem, the same one most IT leaders have. Every year there is a new credential, a new framework, a new exam. In this episode he walks through the tool he uses to cut through that burden, NotebookLM, and shows exactly how he gets from zero knowledge to exam-confident without burning weekends. 0:00 Introduction and the certification treadmillNabil opens with a concrete result: when he took the ISO 42001 exam, it was the first time he felt genuinely confident going in rather than hoping for the best. 0:25 What NotebookLM isNotebookLM is a Google product that lets you upload your own sources, PDFs, URLs, videos, notes, and then interact with an AI constrained to only that material. Three panels: sources on the left, chat in the middle, Studio tools on the right. He is using the paid version, which offers more Studio options than the free tier. 1:10 Loading sources and setting scopeNabil demonstrates with ICS-100, incident command training for his volunteer fire station. He loads four course documents plus his own handwritten notes. The key design choice: by uploading only exam-relevant material, he constrains the AI to a closed knowledge set. 2:15 Why prompting changes everythingNabil writes a custom prompt for each output, for example: "I am taking the ICS-100 exam. Help me understand the knowledge in a way that you are certain I will be 90% ready to pass." He also uses AI to sharpen those prompts before pasting them in. 3:30 Audio overviewsThe audio overview feature converts source material into a two-host podcast format. Nabil generates these and listens while walking his dog. The paid tier adds an interactive mode where he can interrupt the AI conversation to ask a follow-up question. 4:53 How to sequence the toolsStart with a video course or lecture first for foundational orientation. Then bring the material into NotebookLM for the real learning work. Starting with NotebookLM before any foundational exposure produces weaker retention. 5:16 Mind mapsThe mind map gives an expandable visual of the entire subject area. After two minutes on the ICS-100 map, Tad, who had no prior exposure to incident command, could already describe the basic structure."I bet you, if you look at this long enough, you'll be able to break it down for me, and you came into this conversation not knowing what incident command was." 6:15 Flashcards and quizzesFlashcards include a green check (I know this) and a red X (ask me again) mechanic. For quizzes, Nabil always starts on medium difficulty, then creates a harder quiz once he feels ready. When he gets a question wrong, he clicks "explain" and the chat panel shows exactly which source the answer came from. 7:14 Data tables and infographicsThe data table organizes material by topic, objectives, best practices, and source document. The infographic generates a visual summary. For visual learners, this format alone can do significant conceptual work. 9:06 Regenerating outputsEvery Studio output can be deleted and regenerated with a new prompt. On the free tier, regenerations are limited to roughly three per item per day. On paid, no cap. 9:45 Sharing notebooksNotebooks can be shared directly. After Nabil passed the ISO 42001 exam, he shared his notebook with Tad so all the source loading, prompting, and output generation was already done. Key takeaway"This was the first time I ever took an exam that I felt like I actually knew the content really well. I didn't feel nervous. I just felt really confident. And it was this tool that I used."
