— Daniel, Granada Hills, CA on 6/17/2017
Nick is hands down the best statistics tutor!
My name is Dan and I have been with Nick for at least two years. We first met while I was studying Algebra 1 in high school. Nick helped me through that then Algebra 2. I then started attending Los Angeles Mission College in Sylmar. I began again with Nick and he helped me get an A in Beginning / intermediate Algebra. My last two semesters have dealt with Statistics. I passed both Prestatistics and Statistics with an A in both. Math is a difficult subject for me and Nick was most patient, and explained the problems in a real world context that made it so much easier to understand. If you are facing the daunting challenge of probabilities, T  tests, ANOVA and all the other aspects of college statistics, then you can't do better. One other thing about Nick, he is really a nice guy, as friendly as they get.
