This was my experience too. I just did all the questions in the textbook.

I had a book just filled with proofs. After a while, you will get an intuitive understanding of where to go next after each step.

What "Math & Statistics" book? Got an ISBN?

A great math book is Gilbert Strang's "Introduction to Applied Mathematics". Actually anything by Gilbert Strang is worth it.

I would also recommend: http://www.amazon.com/gp/product/0521792851/ref=ox_sc_act_ti...

You could also try out the problems at projecteuler.net

I don't remember the name of the textbook, but any with 1000+ questions would do.
