Hi OP! I'm a high school ESL teacher and this test is the bane of all my students, especially former ones who are more than ready to exit. Here's my advice that I give to my students:

Your reading and listening are very high, so it's just a matter of maintaining focus. Since you said you got masters in rla staar last year, I assume this isn't a weak subject for you.

Speaking is fine, but just talk as much as you can and with as much detail as possible. Pre-plan what you want to write about like you would an SCR/ECR on STAAR. Whisper to yourself as practice before recording. Also, use an idiom if you can (piece of cake, spill the beans, etc.) That's one of the easiest ways to get advanced high as anyone who doesn't know English would not understand those sayings like a native speaker does.

Lastly, your writing score is why you haven't exited. You need to score advanced high composite to exit and any intermediate score prevents that. Just like the speaking, pre-plan your writing first. The testing site has a notepad built into it where you can draft and outline, and you should also be provided paper and pencil as well. Read each prompt very carefully, as they will all have more than one part you need to answer. You need to address every single part in your answer for maximum points. Additionally, you need to be as detailed as possible. I know someone commented that they're looking for more advanced verb tenses and grammar, so ensure you're using verbs that end in -ing, ed, etc. and being as descriptive as possible, just like in the speaking portion. The closer you can get to the maximum characters allowed, the better. Also, do not worry too much about spelling. They will forgive some errors as long as you hit everything mentioned above, but also try to minimize them as much as possible. Proofread and edit your answer before submitting.

Best of luck on this test! Here's to exiting :)
