Choose a certification track to start practicing. Each track includes timed mock exams, full question banks, and per-question explanations.
Foundational Oracle SQL certification covering joins, DDL, DML, subqueries, constraints, set operators, views, and data types.

Database architecture, storage, instance management, undo/redo, memory, security, backup & recovery, archiving, and Data Guard.
Implement and manage SQL-based database solutions on Azure. Performance tuning, HA, security, and automation.
Foundational PostgreSQL certification — schemas, indexes, MVCC, replication, performance, and JSON/JSONB.
The biggest difference between people who pass an Oracle certification and people who don't isn't knowledge — it's pace. The 1Z0-071 gives you under 2 minutes per question. The 1Z0-082 is almost as tight. Untimed study lets you linger on a question for 10 minutes; the real exam will not. The SQLMentor practice exams replicate the exam's time pressure so you build the speed and intuition you'll need on test day.
For best results: study a topic in Learn SQL or Learn PL/SQL, run the related queries in the in-browser editor, then take a timed practice set here. Repeat until you're consistently 5–10% above the pass mark under exam timing — that buffer is what survives nerves on the day.
