They turned it into a frisbee

Another very poor attempt by this particular mathematician. Very few solved exercises, far too many unsolved ones, and the solutions at the back of the book are usually confusing. It is puzzling why this particular, highly successful, publishing house publishes such rubbish.

A bit chaotic. You need to have someone who has worked through the book to be able to guide you. It is not suitable for a student who cannot judge the usefulness of the exercises.

This particular aid is a bit chaotic because it has many unnecessary exercises and does not focus on methodology like some other aids

Tremendous help! It has exercises of graded difficulty, many of which are at a higher level than high school. If someone is interested in practicing, this is the one! My math teacher prefers it over the one by Barla, because that one has very basic exercises, while this one is for the top students!

It does not even explain the solutions to the exercises, in the more difficult exercises it only writes the result or I have to read theory from a textbook, not even pages or chapters, nothing.

Find a book that explains how to solve an exercise because with this it will be difficult for you to understand exercises that you cannot do now

The supplement includes an excessively large number of exercises in each chapter, so much so that in many cases it becomes pointless and chaotic. Obviously, it does not serve as a preparation proposal for the national exams, as it is impossible for the student to solve all the exercises. Also, in my opinion, the applications should focus on methodology and not be burdened with drawn-out calculations that delay and distract the student from the method.
Conclusion: Good for supplementary material, but not as a primary preparation aid for the national exams.

My personal opinion, guys, is that this specific book approaches the absolute in terms of methodology. Each chapter is disgustingly enriched with all possible applications that one may encounter in practice. There are so many applications and the systematic nature of the theory that personally, after a point, I read the subunits of each chapter more as auxiliary applications rather than 'pieces of theory'. The exercises are excellent, with a huge variety ranging from the easiest and basic to the most demanding (way beyond exam level). Of course, the difficulty of the exercises is more increased compared to other similar books, which, however, probably do not even come close to this one in terms of methodology and explanation. If someone is willing to dive in and challenge their mind by reading mathematics, I highly recommend it without hesitation!

Excellent with plenty of examples and exercises and very detailed theory!! I recommend it.. like all the books by Papadakis!

It is a very well-written book with concise theory and solved examples at the beginning of each chapter, with exercises of all kinds. The exercises are numerous and varied, starting with easy ones and then becoming more difficult. It is a very good aid.
