I am a math major in case you two couldn't tell. Math is wonderful, but I think for most people it takes a really great teacher to get past the silly words and funny symbols.
Ofcourse a great teacher is always good. But I strongly believe Math is one of those subjects that can be easily learned even without a great teacher. The only thing that one needs to have to learn math is the willingness to use some brain ....unlike other subjects.
Just in case you missed my Profile,an fyi.... I have a Ph.D and I have extensively used Probability and real Analysis in my research.
