It may also be very worth considering/looking at options for full time study of G/S...I don't think you'll find many people who have completed the studies who won't argue that it's hell on toast...and some find it easier to get through with full timing it, despite loss of earnings!
There have been a few posts I've seen recently with people who have quit distance learning to go full time for exactly those reasons. So I'd suggest looking into it hard before committing to DL to see what may be easier for you....you might be able to borrow one of the ATPL G.S. Manuals from someone to get an idea of how tough they will be for you!
BTW, Bristol database - I'd almost go so far as to say you'd be a fool to not use it...
