The weekends at IIEST Shibpur are different because there are not any classes. Everybody gets a much longer time to try to do the thing they enjoy doing.
A friend of mine used to spend the entire weekend playing Counter-strike or FIFA. Many others also catch up on sleep.
Except for Monday lab report submissions or exams within the Monday morning slot, students usually play, chat, watch movies, enjoy or do whatever gives them satisfaction during the weekend. This spares the weekends that involve INSTRUO or REBECA because the whole student community revels in these two events during that point. Apart from these two festivals, there is no uniformity within the best things that one can do on weekends while studying at IIEST Shibpur. Students just do whatever they enjoy doing which they keep on doing on weekdays too, but just for a slightly longer period.
