Hi guevara, I'd defineately photoread dictionary several times. I don't know if every day for a month would be required, though. I wouldn't worry about activation, though. As far as your english texbooks go, if they are the ones you are using to improve your english then you might want to activate those. If you are learning english on your own, I'd say forget the activation and just photoread SEVERAL dictionaries (both regular types and yourlanguage/englishlanguage) AND SEVERAL english textbooks. Maybe either one every other day for a few weeks. Then watch your progress flourish.
