[!] How to use this list: You do NOT need to do every course listed. Under each section, pick ONE that matches your learning style. Go deep on one path rather than skimming everything. The goal is mastery, not completion.
Phase 01

Python Programming

[i] Instructions - Pick ONE Python is your foundation - everything else builds on this. Choose based on how you learn best. University-style: CS50P. Interactive hands-on: Codecademy. Quick with certificate: see IBM on Coursera. Also follow CampusX and Stanford on YouTube throughout your learning - both are brilliant free supplementary content. Finish one course fully before moving on. Do NOT do all of them.
