The official Oracle APEX Developer Professional blueprint is divided into 7 domains, led by Application Navigation & UI Controls, Forms and User Interactions, and Security & Deployment. The full domain-by-domain breakdown is in the syllabus section above — that is the checklist your study plan should follow.

You can. ExamCost publishes a free PDF demo of the 1Z0-770 practice questions — download it, work through it, and decide on evidence rather than promises. Once you own the full product, 365 days of free updates are included, and an expired product can have its update service renewed at a 50% discount from your member zone.

The 1Z0-770 exam — officially the Oracle APEX Developer Professional — is how Oracle verifies that you can apply its technologies in real working scenarios, and passing it earns you the Oracle Database certification, a credential at the Professional level. Employers recognize it because it is vendor-issued and skills-based. Candidates often continue toward related credentials such as Oracle APEX Cloud Developer Professional (updated/1Z0-771), Oracle APEX Developer Specialist (1Z0-760) once this one is in hand.

You will face 58 questions within 90 minutes on the 1Z0-770 exam. Do the math once and the lesson is clear: dwell too long on a hard item and the clock eats your easy points later. The fix is rehearsal, not luck — take full-length timed mocks in the ExamCost desktop or online test engine until pacing becomes automatic, and learn to flag a question, move on, and return with fresh eyes.

First, delivery: your download is available immediately after payment, and the package also arrives in your email within one minute. If 2 hours pass with nothing in your inbox, check spam and contact support — and feel free to install the software on as many computers as you like, there is no device limit.

Second, the safety net: if you sit the 1Z0-770 exam within 60 days of purchase and do not pass, the ExamCost money back guarantee entitles you to a full refund. File the claim within 2 days of the exam with a scanned enrollment slip and your official score report (PDF); claims are processed within 7 days. The candidate name must match the payer name, and the guarantee excludes exams taken within 3 days of purchase, purchases never used in an actual exam attempt, free materials, and expired orders. If you would rather keep studying, you can swap the product for two free exam packages of equal value and keep the update service on your original purchase.

No formal prerequisites though hands-on experience with Oracle APEX and SQL/PLSQL is recommended

Vendor policies shift from time to time, so treat this as your starting point and verify the current criteria on the official Oracle exam page before you schedule anything.
