Make sure that you do all your housework first. THere is nothing worse than leaving it to get stuck into study and then getting to 5pm and realising that you have a mountain of housework to do as well. It never takes me very long if I do a little bit each day and when do washing, I put a load on, do a bit and then take a break to hang it out. Its not hard to stay on top of it all once you get the hang of it.
