"I Had been noticing that I have been thoughts more fluently.
COuld that be the photoreading ? I ask , because I don´t know if I am realy photoreading.Do you have that too ?"

It sounds like a photoreading effect. The PR process gets you to think about what you're reading, instead of swallowing it whole and regurgitating. Coming from a country where this process of input/output is the norm of the day, I distinctly noted that my attitude towards learning took a more adventurous turn with PR. Extracting ideas makes it easier for you to flexibly apply them. So yes, I did experience something quite dramatic in that area.
Good luck for your exams! Tell us how you get on.
