i didnt do anything for engineering week last year.
it depends on which stream you do - mech eng people last year had to go in for all 5 days to work on some project or something. other streams, like elec, had optional activities you could attend. from what i gathered, cse had some good activities last year.
this year, i was under the impression that it was in week 0 of session2; or have the 12 week semesters killed it altogether?
