I am working on a Kaggle dataset and I am trying to build a predictive model for the "Chance of Admit" (dependent variable) of students to the university of their interest.
Below you can find the correlation among all (independent and dependent) variables. We can quickly observe that only "GRE Score", "TOEFL Score" and "CGPA" considerably affect the "Chance of Admit" variable. So, it makes sense to eliminate all other variables from the predictive model.
Now among the "GRE Score", "TOEFL Score" and "CGPA" variables, we can see that they are all highly corellated (this also makes sense in real life as you always expect a good student to get good grades in these tests). I cannot decide which variables to keep for my final model. Could I keep all of them ? or how do I decide which one to exclude ?
Any help is appreciated.
