Borderline — could go either way

You're inside the noise band around the pass mark, and exam-day pressure usually costs a few points. Don't reschedule yet: the lever list below shows where a week of targeted drilling buys the most points.

Where drilling buys the most points (to 90% accuracy)

  • Cloud Technology and Services (34% weight · now 70%)+68 pts
  • Security and Compliance (30% weight · now 70%)+60 pts
  • Cloud Concepts (24% weight · now 70%)+48 pts
  • Billing, Pricing, and Support (12% weight · now 70%)+24 pts

These sliders are your guess about yourself. The free 10-question diagnostic measures it — per domain, against the same blueprint weights, no signup. Then drill the gaps with the free Cloud Practitioner practice questions and schedule the rest with the study plan generator.

On CLF-C02, Cloud Technology and Services is worth the most: 34% of the score, so lifting your accuracy there by 10% adds about 34 scaled points, while the same effort in Billing, Pricing, and Support (12%) adds about 12. That's 2.8× the return, so if two domains are equally weak, fix Cloud Technology and Services first. The pass mark of 700 works out to roughly 70% blueprint-weighted accuracy on this estimate.
