The study aimed to investigate students' final grades in a linked course or chain course to determine any effect on students' academic performance in their next linked course. Courses with high D, F, and W grades were selected with their subsequent linked courses to form a chain so that each chain consisted of two courses or more. More specifically, Arabic (n = 11,780), English (n = 7,714), and mathematical (n = 1,367) chains were investigated through the years 2012 to 2016. High positive correlations between the grades of the chain courses and the transitional grade are C. Factors were examined to identify any effects on final grades. Findings indicate that 60% to 75% of low-performing students in one link of any chain will demonstrate low performance in the following link.
