About CertLumen

CertLumen helps people pass Databricks, Azure and DevOps certification exams on the first attempt, with lessons, hands-on labs, exam-style practice, timed mock exams, flashcards and an AI tutor, and a pass prediction that says when you're ready to book.

It's built and run by Durga Sai Shashank Adari.

How the courses are made

• Each course follows the official exam guide: every objective it lists is taught in a lesson and practised in questions, in the exam's own section weights.
• Every lesson, question, lab and flashcard is written for practice and checked against the provider's official documentation.
• When a provider changes an exam or renames a product, the course is updated, and What's new in the course says what changed.

What we don't do

• No real exam questions, ever ("exam dumps"). Sharing them breaks the exam providers' rules and the certification you're working for.
• No pass guarantees: the pass prediction is an estimate from your own practice.
• CertLumen is an independent study programme. It isn't affiliated with, endorsed by or sponsored by Databricks, Inc., Microsoft Corporation, HashiCorp, an IBM Company or The Linux Foundation. The exam and product names are trademarks of their owners; they're used here only to say which exams the courses prepare for.
