Act

Hi guys!

I am an international student, and I got 30 composite for the ACT twice with 30 English, 30 and 33 Math, 33 and 30 Science, and 26 and 25 Reading. I have already solved all available tests and in my prep books, and do not understand how I can improve my ACT reading and English scores. While at home, I always get 34-36 for English and more than 30 for Reading, but on the real test, something happens. Do you have some advices? Now, I am reading for several hours every day and hope it would help at least a bit.

Thank you for your answers!
