Review by Prof. Dumitru Buşneag, Dean of the Faculty of Mathematics, University of Craiova, Romania - (book cover):

"This book is the work of an exceptional student -- Corina Tarniţă -- who can look back to her high-school years with satisfaction: talent and hard work led to great accomplishments reflected by her outstanding results at the Mathematical Olympiads."

"[...] nowadays, most students are recommended to study from low-quality books (the only "quality" of such books is that they are filled with trivialities which are "accessible" to most students [...]). Contrary to this general opinion, the present book is a plea for a high-quality mathematics. This is the main reason why I recommend it not only to students but also to professors who feel passionate about the study of mathematics."

Review by Prof. George Vraciu, Professor of Mathematics, University of Craiova, Romania and President of the Dolj Branch of the Romanian Mathematical Society (SSMR):

"An extremely valuable book for all those dedicated to the study of mathematics - the problems are relevant, carefully chosen; the solutions are witty and some are indeed beautiful."

Note: I would like to thank Prof. Iuliana Coravu who provided useful and constructive advice and contributed to selecting some of the problems in the book.
