Ah so our topics are fairly similar. In exams, examiners absolutely love it when you fill your paragraphs with SPEND. In every exam question you do, add as much SPEND knowledge that you're able to. SPEND stands for: Statistics, People and Places, Events, Names (not of people) and Dates. Of course, for every exam question you do, you won't always be able to put all five in, but there's always an opportunity to slip a couple of dates in somewhere.
For 12 and 16 markers, analytical language is key, and they will really push you from a grade 7 to an 8
Use phrases like 'This exaccerbated' or 'This was a crucial turning point' etc
For your 12 markers, do them in order of importance. If the question is asking you to 'Explain why there was a growing concern about poverty under Elizabeth's reign' at the end of each paragraph you need to link back to what's being asked and talk about whether you think issue X was a greater issue than issue Y, and explain why or why not.
For your 16 marker, ALWAYS include a conclusion. Even if you've not completed the rest of your answer and you see that you've got five minutes left, finish off your sentence and go straight to the conclusion.
How to Structure your conclusion:
1) Judgement → wording of the question→why
2) Acknowledge a counter argument → have a debate
3) Judgement → wording of the question → why
I'll provide an example of one of my conclusions that I've previously written:
In conclusion, I strongly agree that the Nazis were quite successful due to the immense amount of resources pooled into staying in control, and indoctrinating the Youth. To name a few, the Hitler Youth Program and the League of German Maidens. On the other hand, it could be argued that Hitler did not entirely consolidate his power, since there was evidence of his failure highlighted through the Edelweiss Pirates and the Swing Kids. Despite the failures in Hitler's regime, it was clear that he was able to tackle the flaws as the rebellious youth were shut down through a number of methods, including the use of concentration camps, beatings, and even public executions. Although the use of these methods are arguably also demonstrations of the failures of Gleichschaltung, overall, Hitler and the Nazis success outweigh the flaws, therefore I strongly agree that the Nazis were quite successful.
Hopefully this is useful, and of course let me know if there's anything else I could do to help
