Why am I getting about half of the student finance I got last year?

I'm about to start my second year at uni, and for some reason I am getting way less student finance. I didn't change any circumstances on my application, so theoretically I should be getting the same amount.
Is this normal? Should I contact SF?

Did your parents submit their household income details for the tax year requested? Is your current entitlement £3,928 by any chance?

Yes, right now my entitlement is 3,928. Last year it was £6847, and nothing has changed in my application.

£3,928 is the bare minimum and is known as the unassessed portion of the maintenance loan. It sounds like your household income hasn't been assessed for some reason, either through fault of your own, or an error at SFE.

Ok, if it was an error of my own, do you know what it is I would have to do to change it?

You'd need to submit your household income like you did last year, and wait for it to he assessed. This can take several weeks to process.

Ok, well I've already sent the online application. I know that last year I got a first letter with the same minimum, then a letter later in September with the assessed amount. Do you think maybe I'm just waiting for that letter again? I just don't want to rely on that being the problem in case I'm wrong and then it's too late to call
