Act weird scores

So I’ve taken the act once in June and I’m a senior now. I got a 27 composite with (26E 28S 18M 34R) however I haven’t really studied English or science because I took an English practice test from the red book (under test conditions) and got a 33 the first time so I must’ve just messed up on test day and the same for the science I got a 30 on my first practice test after the test and I’ve been studying math a lot and have improved from an 18 to a 28 however when I took a reading practice test I couldnt focus on what I was reading and couldn’t finish in time and got a 28 whereas I got a 34 on the real test and had extra time. I take the test tomorrow and I have no idea what to expect
