The focus throughout is the building up of an intuition of calculus before leaping into formulas. Even with uni-level calculus, I did strengthen my intuition of what's going on by reading through his book. It's pretty fun, and I actually spent some time visualizing the calculus of geometric solids afterward i.e http://www.trinco.io/blog/derivative-of-x3 http://www.trinco.io/blog/derivative-of-x3
