Do professors at Christ University (generally) grade harshly?

I'm an upcoming first-year student in Christ University's BSc. Psychology programme and have heard one too many times how difficult it is to score good marks. I was curious to know if good grades are difficult to achieve even for diligent students; are most professors lenient in the evaluation of exams, tests, assignments, etc. or are points docked too easily in some cases? Are 4.0s and 3.6s difficult to come by even after consistent effort and preparation? What is the grading curve like?
