Your university will be divided into faculties, and each one will develop a specific area of Knowledge. We gave a numeric value to these areas of study to measure how can your students learn according to your progress in the game. Every teacher card will show his/her abilities in each field, as well as all the faculties will improve their knowledge level as long as you level them up. Check faculty descriptions to choose the most suitable professors! They should have at least the same value in the chosen knowledge area to optimize your students' performance.
