    Hello @fatimidveil

    That seems fine. They can come twice or many times depending on the rule identified by a decision tree algorithm.

    In the first case: the condition is 

    if (RTM == Yes -->  College Maintenace == No --> Matric == Private -->Mother_Qualification)

    The second condition is 

    if (RYM == Yes, College Maintenance == No --> Matric = Public --> Teacher Response == Some time --> Mother_ualification)

    You can see two branches are different and they are mainly changing based on the vale of "Matric" (Private or Public).attribute.

    This is normal.
