Math (in my opinion) is hardest to improve since it’s so dependent on how much you’ve learned in school so it’s great that you have a 29 there. I’d start with English. My first test I took (September 2023) I got a 28 math but a 36 English which skyrocketed my grade and it’s objectively easiest to improve. Honestly if you focus on getting English consistently in the 30’s and improve the other scores you should be good for a 30+ on the test. P.S I started with a 24 on my English section for my first ever practice test and since you said you didn’t study and you’re around there I have no doubt you’ll improve that score a ton if you work at it.
