Hi!! First of all, thank you for the nice comments you left me yesterday about my graduation
As regards the ppts I have uploaded, I wanted to tell you that the format is a bit different to the original, I made the ppt in a new version of Windows, so when I adapted it, some things changed, for example some words are out of the rectangles where they should be, but you can correct it easily.
So, thanks again for being part of this great site!!
