To be honest, even in western university, they donot specifically give any training on Gauss for lecturer.
You may spend some money to attend some summer schools or you may learn it by yourself.
I learn it by myself and now everything is fine. I can write any model by myself.
Come on, the handout is there, you can find hundreds of different handout, why not just pick up one or two and have a deep reading
that would improve both your guass skill and english reading
