Hello my dears - I would like to say that we are happy to present you with an original project that will break new ground at YKS. AYT Mathematics has always been decisive in YKS. We always say how important AYT is to achieve our goals. There are basically 4 subjects that make AYT Mathematics so distinctive - 15 questions arise from these subjects and they cover half of the AYT Mathematics section. In order to learn the subjects of Limit- Derivative- Integral and Trigonometry in detail and to master all the details - we have thought of a series of essays consisting only of these subjects. Since there are 15 questions from these topics in each AYT exam, each of our attempts consists of 15 questions. We have prepared all the questions with great care, with our team of writers, in accordance with all achievements and the curriculum, taking past AYT exams as a reference. There are also questions that will open your horizons to experiments - truly challenge you and raise your potential. All our students who understand all aspects of the 450 questions in this trial and can solve/understand the solution on their own will put +15 net in their pocket - we believe this wholeheartedly. On behalf of both our students and our publishing house, we would like to thank the authors of our book - my dear colleagues Tolgahan Kaygısız and Emre Polat - our publishing house's mathematics coordinator Ali Alban - for their dedication and meticulousness. Good luck everyone.
