So, based on your process I can see that you are using an ID3 tree builder. I can see that it is building a decision tree based on the PTM attribute and there is nothing wrong with this. One thing I can say is that the PTM attribute is 100 percent correlated with the response variable (college), so there is no need for your tree to make decisions based on other attributes, so it might not use them for tree building. Generally, if some attribute is 100 percent correlated to the response variable, we will be a bit cautious and see if this is not some replica of response that we are trying to predict.
