Should I take the course if I plan to go to BCG/Bain/OW or other consultancies?
Yes. This course is targeted at developing your mental math which will be useful for any case interview in any consultancy, BCG's potential test, and GMAT/GRE. Oliver Wyman test requires advanced knowledge of mathematics, so this course would not be sufficient.
Is this course for university students or for experienced professionals? Who is the typical student?
While there is no reason why a university student would not succeed in this course (and they often do!), most students in this course are experienced professionals. A typical student is a graduate of a Russian university with a major in economics, finance, or a math-related subject and 2-5 years of experience in audit, FMCG, banking, venture capital, or consulting. Exceptions (university students with no experience, unusual work experience, university major not related to math or economics) do occur about 17% of the time.
What homework do you assign?
We have developed over 400 problem sets in Russian based on consulting tests, challenging business case questions and GMAT. The book we offer has 7 sections which will boost your mental math and give you the required knowledge to pass consulting tests and other easier tests (FMCG, Big Four, SHL, Kenexa). At home you will be finishing problem sets from classes (they are long)
What does your progress report look like?
Below is an example of a progress report we share with our students at the end of the course. Every row tracks student's progress for a specific question type and compares it to previous students
Can I buy your book?
No, unfortunately. Our courses are targeted at instruction and mentorship, as well as preparation in a group of likeminded candidates for extra inspiration and motivation. If you only want to practice solving equations on your own, please visit websites of ConsultingGuru, MConsultingPrep, IGotAnOffer, Victor Cheng and others, who have math problems available for purchase online.
How many students will there be in one group?
Up to 10
