(5 stars by Sudhakar Thamodharan)It gives me more great methods to solve statistic problems. (5 stars by henry Yu)This course was a life saver the weekend before my test. Really good refresher training on very important CQE calculations. (5 stars by CCChris Cunningham)I highly recommend Mr. Kumar’s course called “Probability and Statistics – Practice Tests and Solutions.” I am so glad I purchased this and went through each question and understood rationale on the ones I answered incorrectly. After preparing with Mr. Kumar’s courses, I felt very confident on exam day. (5 stars by Christopher Philip)wow!!!!!!!!!!!!!!!!!!!!!!!!! I loved it!!!!!!!!!!!!!! The explanations are very clear and a loooooooooooooot of different examples for each subject are shown. I loved it!!!!!!!!
