Improving ACT results. need your advice

<p>Is it feasible to improve ACT compose score from 25 to at least 30 within a month? I have my test in April. In January my practice score was 16; now it's 25.
The main problem is that English is not my native language. I often spend much time trying to understand the question.
I read the "Baron ACT 36", I practice a lot, I read English and American literature to read faster... But I'm not sure, that I would improve my score when only a month left.
