Last time i did that with the advisor, he was very busy with other students and didnt payme any attention, that is i want to do by myself this time, you know if i can do that or not , please tell me thank you.
Yes you can apply for financial aid on your own. Go to FAFSA.com and everything is explained to you what you have to do. Most colleges want you to do it on your own on the internet anyway. If you get terribly stuck talk to an advisor or call the FAFSA people. They will help you better anyway.
I think that you must talk to the advisor to get the paperwork and then you can mail it in :p but you are going to have to speak with the advisor so try to get used to him/her :p
They usually have a financial aid office, i'd say go in there. You will need to fill out the application for FAFSA online. http://funadvice.com/r/3js7q9a81c#
