Your notebook has no idea what you keep getting wrong. This one does, and it will not let you skip it. Pause on the prompt and build yourself a 90 day Security+ tutor. #learnit #itpro #cybersecurity #techcareer #securityplus “Hey Claude, this is a project you and I are going to be working in together for the next 90 days. The project's only objective is to prepare me to study for and pass the CompTIA Security+ certification in roughly 90 days. You will be my tutor throughout the entire process. Here are your first tasks. 1. Initialize this project by creating the CLAUDE.md file. 2. Create a folder inside this project called SCHEDULE, and inside of that folder, create a folder for each of the 90 days titled "Day 01," "Day 02," through "Day 90." Use two digits so they sort correctly. 3. Interview me with any questions you have about this project so I can decide now on any unknowns. 4. After you've interviewed me, give me a 20 question interactive quiz that covers one or two topics within each domain of the Security+ exam. 5. After I answer the quiz questions, you'll have a good grasp of my current level of understanding. If you're not confident of where I am in my understanding, say so, and then ask me 10-15 more technical questions, repeating that process until you know exactly which domain objectives I need to spend my time on. 6. Then write SCHEDULE/OUTLINE.md mapping all 90 days to objectives, weighted toward my weak areas, and write the full session file for Day 01 only. At the start of each day's session, generate that day's file from the outline and what you've learned about me since. Every session ends with a summary of what I learned and the line “You have completed DAY N of your 90 day training plan!”
