I teach post graduate business management students in universities/ business schools. I handle courses that include Business Statistics, Quantitative Techniques, Marketing Research, Advanced Excel and Business Analytics among others. My priority has always been to make the students understand the concepts, enjoy the learning process and have an appreciation for the subject itself that goes way beyond the immediate goal of passing an examination. I quickly assess the current knowledge level of the students and structure my courses in such a way that the weakest student present in the class is comfortable. I also take care to pace my teaching speed based on the grasping power of the student(s) even if that means taking a few extra sessions
