What happens if I stopped paying my education loan after a 50% amount?
You can't! You can't stop paying your student loans, because they will follow you until you die. They are unbankruptable and you can't run from them. If you default, the government will just garnish your wages, take your income tax refund and, if necessary, take part of your Social Security check. Literally, you will pay until you die. The good news? So long as no one cosigned your loan, it will die with you, and will not be passed along to your kids.
