FAQs
Can I learn AI without math?
To an extent. For serious ML engineer roles, linear algebra + calculus + probability at undergraduate level are needed.
Which first: ML theory or LLM prompting?
LLM prompting — faster ROI, then broaden to theory once you've landed first role.
Do I need to know all 10?
No. Master top 5 (Python, LLM, RAG, SQL, one cloud) for entry-level roles.
Paid vs free courses?
Free courses cover 95% of what you need. Pay for certs only if employer values them.
Fastest path to first AI job?
Python → LLM basics → RAG project → apply = 4–5 months minimum.
Conclusion
Master Python + LLM + RAG + one cloud in 2026 and you can land $130K–$180K roles within 6–9 months. Start with Python today and ship your first RAG project within 4 months.
