(You can find more tips on the vocab and expression side of writing 
here, the original source of this vocab bank).
First... how to actually use these wordsTo challenge yourself to learn and use new words and build a good
/high-quality/superior/better/outstanding/admirable/broad/excellent/varied/wonderful/wide-ranging/comprehensive vocabulary, try these steps!
1.  Write.  Write something, anything, language-analysis-y (we're going to give you heaps of opportunities!), and then go through your writing and list any 'problem' words - words that you commonly repeat, don't quite express what you wanted, or are vague and generic (e.g. 'good').
2.  Collect alternatives.  That's what this is for, and you can also Thesaurus it.  Build up a bank or mind-map of synonyms.
3.  Use them.  Create cue cards with a word you use too frequently on one side, and synonyms on the other; practise verbally coming up with as many synonyms as possible.   Practise writing the words in single sentences of analysis.  When writing essays, have the bank there and refer to it as you go, trying to incorporate new words.  Or, go over essays afterwards and replace weaker words with stronger ones from your bank.
4.  Rinse and repeat.  Often.  No, I don't mean 'write one full essay per two months'; I mean, small and often, because that's the only way to learn the words.  That's where this club comes in super handy 
 5.  Check you're using them right
5.  Check you're using them right.  Its really easy to use new words thinking they mean something different, or trying to fit them incorrectly into the grammar.  Were more than happy to give feedback in this board about this!

In case youve never heard, the examiners HATE formulaic responses.  A language analysis like this:
The author does this, which has this effect.  Then the author does this, which has this effect.  After that, the author does this, which has this effect.  Next the author does this, which has this effect.  Then the author does this, which has this effect. Finally, the author does this, which, you guessed it guys if you read this far, has this effect.will not go down well.  Its repetitive, boring, and doesnt develop any interlinked big-picture understanding of the piece youre analysing.  On the plus side, the rhythm is so repetitive that the examiner will be easily able to snore in time with it.
Here are some good ways to start:
