Each student is provided a Student Performance Report (SPR). The SPR analyses the strong and weak areas of the student and also gives a detailed performance comparison of the student vis-à-vis other students at School, City, Zonal and International level. Analysis of the student’s past 8 years’ performance is also provided.
