Before you even consider getting a student loan, make sure that you have researched the difference between grants, scholarships and loans, all of which come in the category of free financial aid but have different terms and conditions. Seek for a state-financed loan rather than a private one as the interest rate for the former will be lower, with more transparency. Private loan should be your last resort so consider all your options before picking one.
Have a clear understanding of the debt you owe as it will help you determine your budget. Once you know the amount you need to pay each month or annually on the loan, then automatically it will help you to sort out your personal expenses. Categorize them as well, under fixed like rent, student loan fee etc and under variable such as leisure and food.
Also do some saving. It is an essential part of your budget. One tends to neglect this but try to save your funds as it will help you in emergency. Also, get advice from your closed ones who have been in such situation and have managed it successfully.
Depending on your current state, if you are working, then use an income-based option which automatically deducts your loan payments from your salary and further allows you to save a certain proportion. It will clearly reduce the risk of complications.
Establish an understanding of loan cancellation and exemption. Take into account deferments or forbearance if you are unable to pay and want to postpone your payments for the time being. However, keep in loop your lender and preferably get a written notice that your loan payments have been suspended.
