They seem to have missed out the one that exhorts students to obey the university's diktats.
I'm not entirely sure why the students should "use all the resources on offer", as it seems to suggest that none of them are bright enough to excel without going to remedial programming classes, but if it encourages a few more to attend their lectures I'd be happy.
I did try to take a better photo of the poster this morning, but there was a woman wearing an extremely short dress wandering around in front of it using her phone, and I didn't want to arrested for voyeurism.
