My first thought is that you are repeatedly making the same types of mistakes over and over again. You don’t know what you are doing wrong, over and over. I know you don’t want a tutor, but maybe just a couple of sessions will help make a difference. A tutor can help you see where you are going wrong.
I suggest you look at this thread:
A LOT of a student’s test score is that a kid simply isn’t utilizing basic test skills.
I suggest you adjust your expectations for your eventual score. It’s going to be very difficult to raise all the other sub scores by enough points to give you a composite of 34. Also, spend time brushing up on your punctuation skills.
