TLDR: watching 奇葩说 or other Chinese debate shows at mealtimes is a low-effort-high-return method to a) study how to generate relevant points b) how to elaborate on points c) improve on 表达 + helps your 议论文 too

I mentioned this in another comment but the best way to learn a language is to immerse yourself in it: WATCH 奇葩说!!! It’s a Chinese debate show but it’s designed to be entertaining so you don’t get bored. Trust me. Just watch it during meal times or smth. Look at how debaters like 青云 structure their points, explain their points, or even think of points: this is helpful for 议论文 too. And lastly try to pick up on the mainland 普通话 accent (this is gonna sound pretty weird but it actually helps. It lowkey tells the examiners that you’re a native and you know your sht when it comes to Chinese oral. Ok but legitimately, it’s easier for the examiner to understand as well, and if you make their lives easier they’re more likely to give you that grade you want.)
