There are 4 NTU buses, each representing the 4 main schools they
have
SBS 2837 R - College of Science
There's still College of Engineering, College of Humanities and
Social Sciences and Nanyang Business School. Think 2818X is the
latter.
SBS 2822H has the College of Engineering version of
the ad.
SBS 2818 X - Nanyang Business School (confirmed).
Seats also pretty different in a sense SBS 2818 X has the
computer chairs style with enough headrest for some seats and it's
brown in color. Very cool!
