There's no way that I can absolutely prove that the techniques work, especially to someone who lives far away, but I have recently been using some of them in my college studies and I find it much easier now to stay on top of texbook material.
Additionally, the techniques by themselves are not the entire story. Another important component of the system is changing one's attitute towards learning so that the techniques will yield more benefit.
It's at least worth a try, in my humble opinion. I hope my brief message has been of some help. If not, I apologize.
