Her father will not let her get married on the grounds that she should complete her education
Question

                I have received some proposals but my father refuses them, and justifies this by saying that I must complete my education first. I have tried to convince them about my wish to marry and that it will not affect my education negatively. But my parents insist on their opinion. Is it permissible for me to marry without their approval? What shall I do otherwise?.
Praise be to Allah.
    Undoubtedly your father’s preventing you from getting married 
    to someone compatible is haraam. Marriage is more important than study, and 
    it does not rule out study because it is possible to do both. 

    In your situation it is permissible for you to contact the 
    sharee’ah court and tell them what has happened, then after that the final 
    decision is up to the court. End quote.
