SFI is not only excellent for students but also for everyone for the simple reason that it brings financial freedom.Students with poor parents need a tool like SFI to pay their scolarship and get a real job.SFI is excellent !I tell it always,if you want a big income from SFI,it's possible,if you want also a little income it's possible.So a student can use SFI like a second or third income or can use it as a major income.All depends on him !
