One month till ACT

Hey, everyone. I just spontaneously signed up for the ACT in December. I have never taken it before, so I am not expecting like a 35 on my first try. What would be the way to go about studying, given the time that I have left? Are there any strategies that I should employ when going through each section? I took a practice ACT in June and got a 28, so I would assume that would be my starting score for this test.
