Hi. Welcome!
A new Official Guide is coming in June (late May/early June) and we don't know yet what exactly it will have but most likely it will have about 150 new questions (250 for the bundle) compared to the last years 2023-2024 guide (previously these had one year and now they have a range).
Last year the book had no new questions really so it was disappointing and it is possible the new OG will have more than the traditional 150 update per year for the main OG / 250 for bundle.
In other words, 85% of the content will *most likely* remain the same.Keep in mind that the Official Guide / Bundle is just a collection of questions with average quality explanations. The books don't teach you strategies or skills needed to solve those questions, so it is much less frustrating and much more productive if you have a course/book set to go along that actually teaches you how to approach these questions, how to handle timing, etc.
Bottom line - the OG is a must have but it is insufficient on its own. It is just half of the solution and you need something else to pair with it (a book or a course).
