Hi a grounding in Math is required before one takes up a Masters /PG in Machine Learning AI

the key math required is Linear Algebra, Calculus and Statistics

for more infor one may lookup coursera / edx.

What am essentially looking for is refresher crash course in Math covering the above topics

while i have tried reading through some mooc's on www.coursera.org, www.edx.com ...while i seem to digest the material at the end of the day am not able to remember anything.

Hence looking for a tutor / course covering the above topics.

where can i find the above.
