Get matched
Partners respond. Transparent pricing. No surprises.
It depends on your market. Certifications carry weight in consulting, enterprise, and some regions' hiring pipelines; elsewhere a strong project portfolio matters more. The guide lays out both cases honestly.
For a working Java developer, about 8 weeks at an hour a day is a realistic plan for an associate-level exam. Newcomers to the language should budget double.
They test edge cases you rarely hit in daily work: operator promotion, string pooling, exception-handling ordering. Practicing those specific traps is most of the prep.
