Great Beginner Course. There are some parts where there will be frustration, but the forums are helpful. Any type of class involving math and science involves practice and work. Professor is great!

An exceptional course to revise previous concepts. many a times strengthened my previously vague concepts. The interviews and especially the practical videos were very enlightening.
