I would recommend you this:
1) In the L section try to write the answers immediately. Also in the section 4 when they have tough sections with words to write down, don't try to find each particular answer, write some words, phrases that might be useful, it helped me a lot and I use this technique all the time. Sometimes you hear it and you are 100% sure, sometimes not. If you are fighting for every answer, this is your chance.
2) In the R section - highlight everything you think might be useful, dates/names - it will make your life easier.
3) In the W section don't write more than 185 words in s1 and 285 words in section 2. They don't need it, and the more you write, the worse it can get. I also think that in order to get 7.0, you have to score 7.5 in this section, but this is only my guess.
I hope that helps.
