The so-called G 1 is the score of mutual evaluation between students in the same class, with many sub-items, which is similar to the score of comprehensive evaluation. G2 refers to the reflection of your academic performance this year, that is, the average academic performance score after the combination of all subjects and the science. This is an indicator used to evaluate scholarships, and G3 is similar to reward points. If you have served as a student cadre for a year, what awards and honors you have won are all converted according to the standard. But to be honest, there is still no need to take these things too seriously. The purpose of going to college is nothing more than to learn something useful, which will help you find a better job or further study in the future. At school, I didn't care about these things, because it has nothing to do with my current development, hehe.
