The document explains what a PSLE T-score is. It summarizes that a T-score standardizes raw exam scores across subjects by accounting for average score and standard deviation. It is calculated using a formula that sets the average score to 50 and compares individual scores to the average. The T-scores from each subject are added to calculate an aggregate score used to rank students. While grades are A* to F, a student with 3A* and 1A could be ranked lower than one with 1A* and 3As based on their total T-score aggregate.
