As already mentioned above you need to select a training lecture which contains all the text you want to practice. Usually the difficulty of the text is gradually increasing and so most lectures contain various difficulty levels. However, some lectures may just contain a single level and text (eg; a newspaper article to test your skills).
Tal i com s' ha mencionat anteriorment he de seleccionar una lliçó d' entrenament que contingui tot el text amb el que voleu practicar. Normalment la dificultat del text s' incrementa gradualment de manera que la majoria de les lliçons contenen diversos nivells de dificultat. Tot i que algunes lliçons tan sols contindran un nivell i text (pex; un article de diari per a comprovar la vostra destresa).
