If you want to pack a list of items into a single sentence, then these items need to be parallel. What do we mean by items and what do I mean by parallel?
Items in parallel structures include:
Parallel means that all of the items are the same type - all nouns, all verb phrases, etc.

Alternatively the sentence could be written using verb phrases only, again separated by commas:
Accurate parallel structures can help to increase your IELTS score for GRA (they're 'structural'), LR (noun phrases are probably the most common item), and even CC (non-parallel structures are difficult to understand).
Ha! There - I just used a parallel structure built from nouns (GRA, LR, CC)!
