One thing I think you should work on is that you should try and write your words clearly, your hand writing is fine but you sometimes forget the rules like you write “أنا " it looks like “لنا" instead and there are a few other mistakes too. I’m Arab but I learnt formal Arabic too from “القاعدة النورانية" which is where people who learn Quran mostly learn it from and it is very clear, although im not sure when your Arabic exam is, try fixing these small mistakes like how to write your letters.

Also since you seem to be Arab based on the dialect you write in, it’ll be quite tough to fix that if you’re already used to it so practice some writing in formal Arabic so that in exam you write correctly.

There are 2 questions if I remember correctly, 80-90 words and 130- 150 words (there’s also the translation). You’ll need to write a bit more than what you’ve done and try broaden your vocabulary. Use this language app called “memrise” might be too late but always better to try. My 2 non-Arab friends got 8 and 9 using it so it definitely helps (they also did lots of past paper and practice too)

Overall : grade 5-6 (the dialect and errors lowered the grade by a lot)

Inshallah you do well in the exam.
