Practice modes
Timed mock exams: build pacing, endurance, and decision-making under time pressure.
Topic drills: fix weak areas fast (best for spaced repetition).
Mixed review: combine recent misses with high-yield topics to reinforce retention.
Recommended study loop
Skim the syllabus and mark high-weight topics.
Drill one topic at a time (untimed first, then timed).
Review explanations immediately and keep a short miss log.
Run a timed mock to measure pacing and coverage.
Re-drill weak sections, then retake a fresh mixed set or mock.
Timing tip
Use untimed sets for learning and timed sets for performance.
If you keep running out of time, reduce re-reading and aim for a first-pass answer, then review flagged items.

Java SE 17 Developer validates that you can read, write, and reason about modern Java code confidently — including newer language features like records, sealed types, and pattern matching fundamentals.
What you should be able to do
Use core OOP features: classes, interfaces, inheritance, polymorphism, encapsulation.
Reason about types: promotions, casts, overload resolution, and generics variance (? extends / ? super).
Use collections correctly and recognize ordering and mutability characteristics.
Write stream pipelines and choose correct intermediate/terminal operations.
Handle exceptions correctly (checked vs unchecked, try-with-resources, flow).
Understand core concurrency building blocks (threads, executors, synchronization) at a practical level.
