The onlyway to get better at both of these is to practise. Read more and you will find it getting easier. Start with simpler stuff and then up the game as you feel more confident. I would suggest like this:

Short, easy article

Long, easy article

Short, more complex article

Longer, more complex article

Etc etc

Same thing for writing. I found writing case commentaries to be useful practice. Even if you don't publish them your writing will improve and you will learn some more law in the process.
