We are on the home straight (Br. Eng.) or home stretch (Am. Eng.) so here is a little more on the future. Revise paragraphs and passive voice and many other things here, for example, the dreaded articles and whether to use as or like. Check out these essays - the free ones (!) such as this one on capital punishment, although it is incredibly long, and this one on the right to choose your children's school. Keep listening to this and this.
