I wanna know about Css profile plz help me
You need to be more specific with your questions.
There are directions on the Profile form. Use those.
For the 2017-2018 school year application, you will need your 2015 tax returns. You will also need the value of ALL assets the day you plan to submit your FAFSA. You will need the value of your primary home if you own it…and the balance of your mortgage.
Did you do the fafsa already? A good amount of the information you need is on that form.
