How to use this blueprint

  1. Go through the objectives above and mark each one: done for real, only read about, or new.
  2. Start where heavy weight meets the most “new” marks. Discovery Pattern Design and Discovery Configuration are 35% each.
  3. Build each objective in a Personal Developer Instance rather than only reading about it.
  4. Use practice questions to find weak domains, then go back to those objectives and their documentation.
