“…Bray (2013) pointed out that students who did not pay for PT were likely to repeat their grade because schoolteachers were responsible for designing and rating the end-year examinations. In addition, teachers were more inclined to favour their tutees not only during classroom learning activities but also for examinations by giving them more care, emphasising tests during PT prior to the test date and giving tutees higher scores (Bray, et al, 2016;Bray, et al, 2018;Bray, Liu, Zhang, & Kobakhidze, 2019;Edwards, Le, & Sustrarsic, 2019). Some teachers would also allow tutees to cheat during the examinations as well as make fun of non-tutees in class (Maeda, 2019).…”
