Something for all of Batch 2011.
[Here] is the schedule of English period rehearsals, including a couple of UB rehearsals.
Some sessions kind of got bulldozed by the 4th year Theater Arts classes, though.
Here is the chart of schedule conflicts. I did my best to give everyone an equal amount of English rehearsal sessions.
In any case, all the sessions in the Excel file above are indeed blocked off, and if you really have to trade sessions, you might want to try practicing those diplomacy skills of yours. Otherwise, you have to look for sessions outside of those days.
