OCI 1Z0-1122-25 Study Plan: 30, 60, and 90 Days

OCI 1Z0-1122-25 30-, 60-, and 90-day study plan with topic order, review loops, and final-week priorities.

This plan is built around the fundamentals loop: classify the task -> choose the metric -> check failure modes -> route governance and monitoring.

How to use this plan well

Each study block should do four things:

  1. classify the issue as data, evaluation, GenAI, governance, or lifecycle
  2. choose the metric, control, or concept that belongs there
  3. do a short scenario or mixed set
  4. write down whether the miss came from data quality, wrong metric, weak grounding, or ignored governance

	  Classify["Classify data / evaluation / GenAI / governance / lifecycle"] --> Choose["Choose metric or control"]
	  Choose --> Drill["Do short scenario set"]
	  Drill --> Review["Review why misses happened"]
	  Review --> Classify

How long should you study?

Typical candidates need 25 to 55 focused hours.

Your time Recommended timeline Good fit
10 to 12 hrs/week 30 days intensive path with some prior AI exposure
5 to 7 hrs/week 60 days balanced path for most candidates
2 to 4 hrs/week 90 days part-time path with slower reinforcement

30-day intensive plan

Week Focus Output
1 AI and ML basics, problem framing, data quality, and task types fundamentals notes and short drills
2 metrics, leakage, imbalance, overfitting, and evaluation design metric tie-break sheet
3 GenAI basics, grounding, retrieval, and hallucination control weak-lane notes and mixed sets
4 responsible AI, privacy, fairness, monitoring, and final compression mixed review and readiness check

60-day balanced plan

Phase Weeks Focus
1 1 to 2 lifecycle basics, task framing, and data-quality thinking
2 3 to 4 metrics, leakage, overfitting, and evaluation logic
3 5 to 6 GenAI basics, grounding, retrieval, and answer-quality judgment
4 7 responsible AI, privacy, fairness, and monitoring
5 8 weak-lane repair and mixed review

90-day part-time plan

Month Focus Goal
1 vocabulary, task framing, and lifecycle basics stop losing points to term confusion
2 data and evaluation logic get stronger at metric and failure-mode judgment
3 GenAI, governance, and exam-style tie-breaks finish with mixed-set confidence

If misses cluster here, do this next

Miss pattern Weak lane Fix next
you choose the wrong score or trust accuracy too fast evaluation review precision, recall, F1, AUC, and task-fit logic
you trust great offline results too easily data and evaluation review leakage, split design, and held-out validation
you blame the model when the context is weak GenAI review grounding, retrieval quality, and supported answers
you skip fairness, privacy, or safety governance review responsible AI controls and operational ownership

What strong prep usually does

  • classifies the problem before naming a technique or product
  • keeps confusion tables for leakage vs overfitting, accuracy vs F1, and grounding vs fine-tuning
  • writes down why the winning answer is safer or more aligned with the task instead of memorizing AI buzzwords
  • uses Oracle docs to settle disagreements, then comes back here for compression

Final 72 hours

Keep doing Stop doing
rereading the cheat sheet and glossary opening unrelated new AI tools or framework tutorials
reviewing weak-lane notes and confusion pairs treating every question like a product-feature question
checking Oracle docs for disputed boundaries building a large late-stage AI lab
practicing data -> metric -> model -> governance order trusting unsupported community summaries over Oracle docs

Route yourself well
