Phi8
is the Math Review , Verbal Review and DI Review chapters in the Official Guide sufficient to learn the required fundamentals ?
Hi
Phi8, imho no. The contents in the three review books (or actually in the main OG, as they are the same) are quite high-level, without going into much depth.
I believe you can "taylor-made" your own version of the study plan, by supplementing other materials for learning topical concepts and strategies.
For example for Quant, you can use the GMAT Club Math book, which is a free pdf download. Or you can use Bunuel’s heroic quant guide:
ultimate-gmat-quantitative-preparation-guide-244512.htmlFor Verbal, actually GMAT Ninja’s videos on Youtube are excellent already. But you can also supplement with, for example,
Manhattan Prep’s RC and CR guide, which you can get 2nd-hand from eBay for like 10 bucks a book. I even know someone using PowerScore LSAT Bibles for the CR and RC content.
For DI, there is not much other resource out there. GMAT Ninja’s Youtube playlist on Youtube is one of the best.
