At the same time, maybe?

Someone had tried to correct the error. We're learning English.

Found this sign at a university building, which is only for students at the department of science and engineering. I cannot help but wish I would be one of the students every time I come to their building, which looks quite modern and open, comfortable to stay in as the extra shows, not like the one for humanity students. Also the structure of it somehow reminds me of a library of a university where I was during my time in Britain.
