In Ramsey theory, a set S of natural numbers is considered to be a large set if and only if Van der Waerden’s theorem can be generalized to assert the existence of arithmetic progressions with common difference in S. That is, S is large if and only if every finite partition of the natural numbers has a cell containing arbitrarily long arithmetic progressions having common differences in S.
My experience at MBAGuru has been exceptional. The faculty members are well versed with their subjects and take immense care in imparting required knowledge. The class structure are such that it gives you adequate time to comprehend the topic, practise enough questions within the class itself and be able to rate your performance against that of others. Moreover, with the adaptive preparation, it is possible for you to judge your stage of preparation in all the topics and improve upon it, if required, through various levels of questions. The GD and PI classes are extremely beneficial too and prepare you well for all the scenarios that you may face. All in all, it has been an enriching experience.
