Is going to Germany for financial gains on student visa is a prudent decision?

Like almost all Pakistanis, I too want to leave the country. I wasted the last 3 years attempting CSS but I just failed the CSS essay on 6 marks. Now, I think I will be wasting my time here in Pakistan and its not for me. So from the title, is it wise to do so? And I don’t have money so I will be taking loans for it. And anyone have any idea in how much time, I can earn back that something like 5 million pkr? and is the path to citizenship easy when my student visa expires? Thanks
