Parental income has dropped massively, I am entitled to anything?

So, basically, I'm a bit clueless about all this as previously we didn't even bother submitting my parents' earnings because we knew I wouldn't qualify for the maintenance grant. Long story short, however, my dad's income (which is our main source) has dropped massively in the last three years (he owns his own business), to the point where I'd be entitled to full grant where I wasn't entitled to anything before. But when I looked at the forms online, it seems to go on tax years that are a couple of years back, which obviously make us look like we have more money than we actually do. Is there any way of getting grant based on 'real' income - ie current? Or am I just not entitled to anything?

This is what you do.
You apply for an income assessed laon and provide evidence for 2009-10 as requested.
You wait to be assessed then you download the current year assessment form.
Your folks fill it in with estimates for income for 2011-12 and send it off.
You get reassessed and your folks need to provide evidence at financial year end 2011-12.

you still have to apply with 2009-10 info first though, or at least that's what I had to do.
