I think it will definitely be worth your while to spend some quality time on this book.
For example -- the strategies for tackling tough DS problems are very well laid out -- the authors explain a number a common traps people fall into and present a number of excellent examples. So it will be best to not rush through the book -- take your time to actually understand the concepts and do all the practice problems. The explanations are also really detailed -- so make sure you spend a lot of time reading them. They break down DS problems methodically -- so there is quite a lot to be learned from the explanations as well.
I spent about 3 weeks in total on the book (I plan on spending more time in the near future to review the contents again). Aside from the chapter problems -- there are 150 high quality practice problems at the end of the book. Some of these problems will take you more than 2 minutes -- a couple of the DS questions took me a "long" time to solve.
And as far as the level and the percentile and stuff -- I'm not too sure about that. But I'm pretty sure you will benefit from it and see some tangible results. I have done some practice CATs -- usually score fairly decent in Math. But my DS strategies were mostly down to picking numbers and "estimating" and "approximating". I felt that the advanced book really helped me come up with better ideas to tackle DS problems and of course a more methodical and organized approach overall.
I also struggled a bit with advanced number properties questions -- like absolute values and inequalities -- My approach was often reduced to plugging in values (-2,-1, -1/2, 0, 1/2, 1, 2) -- and this is OK -- but it is not always efficient. Sometimes there are just too many variables and cases to consider. So I had to learn how to solve complex inequalities and algebraic expressions quickly and confidently -- the advanced book has some good problems to practice and improve in those areas.
The toughest questions on the Math section are hybrid problems. For example -- problem 229 on OG 12 -- I can tell you for a fact that a couple of months ago there was no way I could have confidently solved a problem like that in a limited amount of time. But after dealing with a bunch of problems like that -- it's not so intimidating anymore. The advanced guide says -- put pen to paper -- move your pen -- write the information down -- get your brain fired up -- draw a diagram -- look for a pattern etc. All this was great advice for me -- because I would often read a problem and try to come up with a mental solution first and then start solving.
Good luck with the book. I really enjoyed it -- it was brutal at times but well worth it.
