Preparation Journey

A practical, step-by-step summary of how I prepared for each certification — what worked, what didn't, and the exact resources I used. Use this as a checklist or jump to the areas you care about.

Quick Timeline

  1. Week 1–2: Foundation — review core concepts & terminology.
  2. Week 3–6: Hands-on labs — build small projects and follow guided labs.
  3. Week 7–8: Practice tests — simulate exam conditions and review gaps.
  4. Last 1–2 weeks: Rapid revision & targeted practice on weak areas.

Resources I used

  • Official docs & exam guides — read first, always.
  • Interactive labs (Qwiklabs / Cloud Skills Boost / sandbox projects).
  • Practice exams — official and community mock tests.
  • Concise notes & flashcards for quick revision.
  • Community threads — clarifications and edge-case discussions.

Practical tips

  • Do hands-on labs before reading advanced topics — practical context helps retention.
  • Timebox practice exams and review incorrect answers immediately.
  • Keep a short 'cheat sheet' of commands/console flows you use often.
  • Teach someone else — explaining concepts exposes gaps quickly.
  • Don't cram. Plan spaced repetition over weeks, not days.
