I am taking the test one last time on October 24th without writing. 
How can I improve my score to at least a 31-32?
Man, we’re really similar. I got a 30 this September and I had little prep prior to taking this test. I think the problem for me was that I practiced with easy materials (real red ACT book and PR’s). So I am going to buy Barron’s and study ham and hope for a better score. Hopefully we both improve and conquer the ACT! lol
Your best bet is to focus on science. It is dragging down the composite.
