There was less than half a minute until class officially started.
When Zhao Yanzi sneaked in from the back door, Hao Ren's classmates turned around to look at her.
University courses were normally split between 'big classes' and 'small classes.' A few classes would merge for a big class, and these big classes were usually introductory or mandatory courses for a specific program.
Each program had their small classes, and these small classes were usually practical courses like engineering design which required specialized equipment.
First-year and second-year courses consisted mainly of introductory courses, so several classes would be merged for them. However, third-year and fourth-year courses focused on individual programs, and there were differences within programs. Therefore, the teaching material would be different, and not many people were in each class. The teachers were stricter, so it was harder to skip classes or have people sit in for others.
