Access to Richard Berry building after hours?

[asterio]

Most of you might have been through this already: every weekend you manage to finish the math assignment, but YOU CAN'T HAND IT IN, because bachelor students are not allowed to access Richard Berry buildings after hours.

then you have to wait until Monday morning, wake up extremely early to get to uni just for handing in one assignment, then you get really tired in the afternoon and learns nothing from lectures...
(I live 1 hour away from uni...)

I really wish lecturers could understand how frustrated this is... And if anyone knows a way into the building after hours, please let me know, much appreciated!!

For all undergraduate students, no after hours access is provided.  For postgraduate mathematics and statistics students, upon enrolment, they are given access 24-7.
