It is primarily focused on the SDLC and where security fits in. The official book does mention the more technical topics like SQLi, validation, etc., but it is brief and the focus is more on the high-level SDLC topics.
I have not taken it yet but plan to do so in the next two months. I did pick up the official guide and have been working through it. Debating whether or not the official practice exams are worth the price.
