The SQLD exam does not use a question bank system, and past exam questions are not made public.

That's why we personally reconstructed the questions vividly by recalling them immediately after the exam.

It is structured in a way that will elicit reactions like, "It contains only the actual exam points!"


👉 At the actual level of difficulty
