1 - practical classes will take place as usually

2 - theoretical classes will be used for extra practical classes, taking place at the LTI classroom. 
In this sense:

students from the Wednesday shift plus the first half of the students from the Thursday shift should attend the Monday theoretical class, that will take place at LTI.

students from the Friday shift plus the second half of the students from the Thursday shift should attend the Thursday theoretical class, that will take place at LTI.

Thank you for your attention.
