So I just got my SQL - Structured Query Language certification results back this morning and I'm honestly still in shock. Passed with an 84% after bombing it twice before (72% and then 69% — embarrassing). I'd been studying off and on for about four months but never really had a structured approach, just kind of reading docs and watching random YouTube videos.
What finally clicked for me was treating it like actual test prep instead of just "learning SQL." I started using a proper SQL Practice Test to identify my weak spots, and it turns out I was terrible at joins and view management — topics I thought I understood but clearly didn't under timed conditions. The SQL - Structured Query Language practice test format really mirrors what you'll see on the real thing, which helped a ton with pacing.
The two areas that tripped me up most were multi-table joins and subqueries. If you're preparing right now, don't skip those. I'd spend at least a week on each. Anyone else here working toward this cert? Happy to share my full study guide breakdown if it helps.
